However, when conducting research online, certain sampling problems arise that may affect the reliability and generalizability of the results obtained. The modern practice of preparing and conducting social and especially sociological research is almost unthinkable today without the use of a selective method. Conducting Internet research requires special attention to sampling problems in order to minimize their impact on the reliability and generalizability of research results. A systematic approach to sampling and the use of various methods to overcome possible distortions will improve the quality of the data obtained and improve the quality of the study as a whole. With the development of the Internet and an increasing number of users of online platforms, conducting Internet research is becoming more and more popular. However, this area of research has its own characteristics and problems, among which the problem of sampling is particularly relevant. The sample in Internet research may be distorted due to insufficient representativeness, selfselection of respondents, as well as due to incorrect selection of the studied groups. In this course work, we will consider exactly what problems arise when forming a sample for Internet research, and what methods can be used to solve them. The purpose of the study is to study the problems of sampling for online surveys. Research objectives: – to consider the theoretical aspects of the concept of internet surveys in the marketing research system and the rules for their development; – develop and conduct an online survey; – to analyze the main sampling problems for online surveys. The object of the study is an online survey as a marketing research tool. The subject of the study is sampling problems for online surveys. 3 CHAPTER 1. THEORETICAL ASPECTS OF THE CONCEPT OF INTERNET SURVEYS IN THE MARKETING RESEARCH SYSTEM AND THE RULES FOR THEIR DEVELOPMENT Online surveys are a convenient and effective way to gather opinions and feedback from the target audience. With the development of Internet technologies, conducting surveys in an online format is becoming increasingly popular among both businesses and public organizations. Online surveys provide an opportunity to obtain data from a large number of participants in a short period of time. At the same time, conducting surveys in digital format saves time and resources compared to traditional methods such as telephone surveys or field surveys [4, p. 34]. The process of creating an online survey is very convenient and simple. There are specialized platforms and services that offer a wide range of tools for creating surveys, as well as analyzing the data obtained. At the same time, you can choose from various types of questions (open, closed, multiple choice, etc.), customize the logic of the survey and the design of the survey forms. The advantages of online surveys are obvious. They provide quick feedback, allow you to collect data in almost real time, and also allow you to participate in surveys even for those who are in remote regions or abroad [6, p. 19]. However, it is worth remembering the need to formulate the survey questions and objectives correctly in order to get reliable results. It is also important to take into account the audience of the survey and approach the conduct of surveys responsibly, respecting the principles of ethics and confidentiality. Thus, online surveys are an effective tool for collecting information and feedback from the target audience. A properly organized online survey can help a business or public organization make informed and considered decisions, taking into account the opinion of its target audience. 4 Sampling is one of the key concepts in surveys that allows you to get a generalized idea of the opinions or preferences of the target audience. In today's world, with the development of technology and the Internet, online surveys are becoming increasingly important, which allow you to collect information quickly and efficiently. A sample in online surveys is a set of participants who represent a specific group of people or target audience. This sample should be representative, that is, reflect the common features and characteristics of the entire group, so that the survey results are reliable and objective [8, p. 91]. The essence of sampling in online surveys is that it allows you to collect data and receive feedback from the target audience without the need for traditional surveys. Online surveys allow you to reduce the time and cost of collecting information, as well as give participants the opportunity to answer questions at a convenient time for them. In order for the selection in online surveys to be effective, several important points must be taken into account. First, it is necessary to clearly define the purpose of the survey and select the audience that is relevant for this purpose. Secondly, attention should be paid to data collection and information processing methods in order to avoid distortions and errors. Thus, the concept and essence of sampling in online surveys play an important role in obtaining reliable information from the audience. A well-chosen sample allows you to obtain objective results and make informed decisions based on the data collected during the surveys. Conducting online surveys implies the formation of a sample, during which the contact audience is determined, which the conducted research will focus on. This issue is considered to be particularly important [11, p. 45]. The sample should be representative (have a sufficient degree of representativeness to the target audience) and should not be biased. It is possible to ensure a sufficient degree of representativeness only if the target audience is sufficiently represented in the Internet environment. Today, this condition 5 does not seem impossible due to the increasing number of Internet users who are consumers of various products and services. But it happens that there are not enough users on the Internet for a particular product, and then it is very problematic to provide a representative sample. The uncertain representativeness of the sample may be due to the fact that many respondents consider incoming e-mail messages as spam and delete them. This problem is solved by placing an announcement containing an offer to participate in the survey: 1) on the websites of providers of a specific market; 2) on the websites of popular mail systems in specific regions [9, p. 47]. To ensure the representativeness of the sample, it is advisable to follow the algorithm: 1) post an announcement about the survey; 2) register those who wish to participate in the survey; 3) collect information about all potential participants and create a database about them; 4) send invitations to participate in the survey to each of the potential respondents; 5) collect and filter the results [13, p. 32]. The unbiased sample is provided by a sufficient number of representatives of the Internet audience in the total number of the audience that is of interest to the company. Their number should be as close as possible to the general population. This is important because of the low control during the implementation of the study due to the lack of direct contacts between respondents and interviewers. This leads to an increase in refusals from the questionnaire and, accordingly, to a decrease in the number of responses. There is also some possibility that distorted (untrue) information will be received from respondents or the answers will turn out to be incomplete. If stimulating factors are used in conducting surveys (prizes are awarded, participation in the study is paid for), it is necessary to prevent respondents from filling 6 out the questionnaires again. The control is carried out by tracking the IP addresses of respondents, checking the correctness of filling out questionnaires. It is advisable to take into account the fact that only the most active Internet users participate in the research. To increase the number of participants, the use of the roar-ir method is practiced. It consists in the fact that every tenth (or thirtieth, fiftieth, etc.) visitor to the website opens a small window on top of the main page with an invitation to participate in the survey [2, p. 29]. At the current stage of technology development, researchers have increasingly begun to come to the aid of online surveys. This is a really convenient and economical way to collect primary information. The organization of an online survey is not much different from the organization of a classical sociological study. The most important part of the survey process is to create questions that accurately measure the opinions, experiences, and behavior of the public. An accurate random sample will be wasted if the information collected is built on a shaky foundation of ambiguous or biased questions. Creating good measures involves both writing good questions and organizing them to form a questionnaire. Questionnaire development is a multi–step process that requires attention to many details at once. Designing a questionnaire is difficult because surveys can ask questions on topics with varying degrees of detail, questions can be asked in different ways, and questions asked earlier in the survey can influence how people answer subsequent questions. Researchers are also often interested in measuring changes over time and therefore should be attentive to how opinions or behaviors were measured in previous surveys [10, p. 36]. Interviewers may conduct pilot tests or focus groups in the early stages of questionnaire development to better understand how people think about the problem or understand the question. Pre-testing the survey is an important step in the questionnaire development process to assess how people respond to the general questionnaire and specific questions, especially when the questions are entered for the first time. 7 For many years, surveyors have approached questionnaire design as an art, but significant research over the past forty years has shown that there are many sciences involved in developing a good questionnaire. Here we discuss the pitfalls and best practices of questionnaire development. Researchers always hope that the answers received on the survey questionnaire will provide useful data. If the questionnaire is too complicated, there is a fair chance that the respondent may get confused and drop out or answer inaccurately. You can try out several different survey options to determine which one resonates best with your target audience. Pre-testing is a good practice, because the creator of the survey can understand the initial stages if any changes are required in it. The structure of the questionnaire includes the following elements: service field, introduction, body of the questionnaire, classification part, conclusion. The design of the survey depends on the type of information that needs to be collected from the respondents. Qualitative questionnaires are used when there is a need to collect research information to help prove or disprove a hypothesis. Quantitative questionnaires are used to verify or verify a previously generated hypothesis [3, p. 81]. However, most of the questionnaires follow some essential characteristics: uniformity, research, question sequence. Stages of the questionnaire development. The first stage is the creation of a research program or a preparatory one. Defining the problem, object and subject of research, setting goals and objectives – all this work is done in exactly the same way as in classical sociological research. The first stage also includes the development of a sample and tools. The sample for online research is calculated based on the number and characteristics of the panel. Large companies have numerous panels and know certain socio-demographic characteristics. According to ESOMAR recommendations, this list includes: - gender; 8 - level of education; - family size; - region; - location (zip code + house number); - age (date of birth); - presence of children in the family; - employment; - the amount of internet usage (hours per week); - type of internet access [5, p. 37]. Further, the questionnaire for online research has the same structure as for the classical one, but there are certain criteria that should be followed: • The wording of the questions should be clear to everyone, that is, the question should be made as simple as possible, because, unlike offline surveys, when the interviewer is interviewing, there is no one online to explain the meaning of the question; • The number of questions is limited – the more there are, the more likely it is that the respondent will simply stop answering halfway; • It is advisable to do without tabular questions – again, this is so that the respondent does not get confused; • The Internet provides the opportunity to include multimedia elements in the survey – photos, videos, sound – this is a big plus that should be used to keep the respondent's attention [7, p. 56]. In classical sociological research, the final point in the preparatory stage is the recruitment of interviewers and their instruction. In Internet surveys, it is still necessary to work out software that will replace all interviewers. This is done by a software specialist, most often several people. They make up a questionnaire and a way to process the data. 9 The second stage is operational and procedural or field. This is where the actual collection of information begins. To begin with, there is a mailing list by e-mail with an invitation to participate in the survey and a link to it. The mailing list goes only to those addresses that correspond to the quota and the sample. The European Society for the Study of Public Opinion and Marketing (ESOMAR) has compiled the following principles of the Internet survey: • Voluntary cooperation. • Providing information about the organizers of the survey and a contact phone number or e-mail. • Ensuring the anonymity of respondents. • Data security. • Unauthorized mailing [14, p. 63]. The data obtained during the survey is saved in the program and can then be exported to, for example, SPSS. It is also sometimes possible to get intermediate results before the end of the survey and final summary data. Most often only one-dimensional, less often two-dimensional tables. And here we move on to the third stage – the resulting one. To study the results of the study in more detail, you simply need to export the data to a suitable program for processing them. This is necessary for detailed analysis, identification of dependencies, and so on. The stage of data analysis and writing an online research report is no different from a similar stage in classical sociological surveys. Thus, if you follow the rules and stages of the questionnaire development, then a carefully and precisely designed questionnaire helps to collect reliable information on the research topic for its further development. 10 CHAPTER 2. PRACTICAL PART: DEVELOPING AND CONDUCTING ONLINE SURVEY 2.1. Description of the online survey We have developed a questionnaire and conducted a study of consumer preferences in choosing sportswear and shoes. In order to study consumer preferences in choosing sportswear and shoes, a marketing study was conducted in February 2024 using a questionnaire survey. Research methodology. And so, 50 people took part in the survey. To begin with, we found out how various factors affect the sale of sportswear. As it was revealed, 37 people, or 74% of the respondents, are in the age range of 15-18 years. Between the ages of 19 and 24 – 24% of the respondents, or 12 people. Only 2% of the respondents, that is, 1 person, is aged 41 years and older. Of the respondents, the main share is occupied by women, namely 76% of the respondents, or 38 people. The remaining 24% of the respondents, or 12 people, are male (Figure 1). Figure 1. Age and gender of respondents The survey was conducted using a specially designed questionnaire, which is presented in Appendix 1, by distributing the forms to the city's population and subsequent processing of the data obtained. During the survey, information was revealed on the main blocks of questions: how often do people play sports, which brand 11 is the leading one, whether promotions affect the volume of purchases, what is the purpose of buying sportswear. Answering the question: «Do you play sports?» - 94% of the respondents, or 47 people, answered positively, and only 6% (3 people) answered negatively, as can be seen from Figure 2. Figure 2. Respondents' sports activities To the question: «How often do you exercise?» 30 of the respondents replied that they exercise several days a week, which is 60% of the respondents, that is, most of them. Of the 50 people surveyed, 22%, or 11 people, replied that they rarely exercise. The remaining 9 people, or 18% of the respondents, turned out to exercise daily (Fig. 3). Figure 3. Frequency занятия спортом of people's sports activities 12 Исключительно самостоятельно приобретают одежду и обувь спортивную 82% of respondents, or 41 people, purchase sports clothing and footwear exclusively on their own или 41 . The remaining 9 people do not buy самостоятельно this product on their own, which is 18% of respondents (figure 4). Figure 4. Buying sportswear and shoes by young people Thus, we have developed and conducted an online survey. 2.2. Analysis of the conducted online survey The main results of the marketing research that we received during the survey are as follows. To the question: «How often do you update your sports wardrobe?» 21 people, which is 42% of the respondents, replied that they update their sports wardrobe every six months. We can say that this is quite common for the average person. For several years, 13 people out of 50 respondents, or 26% of the total number of respondents, have been wearing sportswear and shoes. Every year, a fifth of the respondents, or 10 people, update their sports wardrobe, which is 20% of the respondents. 6 people out of 50 respondents, or 12% of respondents, update their sportswear wardrobe monthly (Fig. 5). 13 Figure 5. Frequency of purchase of sportswear and shoes Of the 50 people surveyed, 32 people, or 64%, noted that they buy sportswear and shoes, mainly for training, that is, this is the majority of respondents. The remaining 18 respondents, which is 36% of the respondents, purchase sports items for everyday wear and life in general (Fig. 6). Figure 6. The purpose of buying sportswear and shoes The following questionnaire question was asked to the respondents in order to clarify their preferences and attitudes towards sports clothing brands. As it was revealed, 19 out of 50 people surveyed, that is, more than a third of people, or 38%, give their preference to NIKE. Of the same number of respondents, 12 people, or 24% of respondents, which is almost a quarter of the respondents, chose REEBOK, therefore, we put it in second place among young people. 7 of the respondents chose 14 ADIDAS, which was 14% of the respondents. This gives reason to give ADIDAS the third place. DEMIX took the fourth place in our rating, as 3 out of 50 respondents, or 6%, chose this particular company. Only 1 person out of the respondents chose PUMA. As a result, 8 people, or 16% of the respondents, prefer other brands of sportswear and shoes (Fig. 7). Figure 7. Preferences of sports brands by consumers Next, we tried to find out which part of the sports wardrobe is most often bought by the respondents. Of the 50 respondents, 27 people most often resort to buying sneakers, which is 54%. About 26% of the respondents, or 13 people, often buy sportsstyle T-shirts. Out of 50 respondents, 4 people often prefer tracksuits, arguing that it is a convenient purchase, which is 8%. And the remaining 6 people, or 12% of the respondents, mostly buy some other types of sportswear and shoes, for example, it can be: leggings, swimming trunks, hoodies, shorts and other sportswear. It was also noted that the respondents have different appropriate wardrobes for various sports activities, that is, different types of clothes for different sports, which is a convenient solution. Also, the clothes are different for different seasons, seasons and weather. 15 Figure 8. Sportswear and shoes often purchased by consumers Analyzing the dependence of the promotion policy on the purchase of sportswear and shoes, it was revealed that the most attractive advertisement, in the opinion of the respondents, is the advertising of NIKE 38% (19 people). 34% (17 people) voted for REEBOK advertising.18% (9 people) voted for ADIDAS advertising, and 10% (5 people) attracted the attention of advertising from other manufacturers of sportswear and shoes (Fig. 9). Figure 9. Sports brand advertising preferences from a consumer perspective Out of 50 respondents, 30 people believe that для них the brand is important for them бренд when buying спортивной sportswear, which is 60% of respondents and is quite высоким high. For 40% of the respondents, or 20 % of the remaining people, the 16 brand is not important, for them важно the quality покупаемой of the clothes they buy is more important than the name, as shown in Figure 10. Figure 10. Brand influence on the choice of sportswear and footwear buyers Of the 50 people surveyed, 40 respondents said that discounts and promotions affect the volume of their purchases спортивной of sportswear and shoes. The remaining 20%, or a fifth of the respondents – 10 people -said that they are not affected (Figure 11). Figure 11. Impact of discounts and promotions on the choice of sportswear and footwear buyers 17 We decided to find out where mostly young people buy clothes and shoes. As it was determined, 31 people out of 50 respondents, which is 62%, buy sportswear and shoes in shopping malls. In specialized stores, their location does not matter, 9 people out of the 50 surveyed, which is 18%, purchase sportswear and shoes again. In online stores, 6 people of the respondents, or 12%, prefer to swim in sportswear and shoes. Basically, this is the working part of the respondents. The remaining 4 people out of 50 respondents, which is only 8%, like to go specifically to the market to purchase sportswear, shoes and goods. All the results obtained are shown in the diagram in Figure 12. Figure 12. Place of purchase of sportswear and shoes Two fifths of the respondents, which is 40%, or 20 respondents, replied that the range of their spending in a sports store ranges from 3,001 to 5,000 rubles per trip to the store. That is, they are really ready to part with this amount at one time in a sports store, which is a high indicator. Slightly fewer respondents, namely 14 out of 50 respondents, are willing to spend from 5,001 to 10,000 rubles per visit to a sports store, which is 28% of respondents. 11 people out of the respondents, or 22%, set their limit to 3,000 rubles for going to a sports store. The remaining 5 respondents, or 10% of respondents, can afford to spend more than 1,000 rubles in a sports store per visit (Figure 13). 18 Figure 13. Cost range обновления of sports wardrobe upgrades Having asked the respondents about their hobbies, of course, specifically sports, the following answers were received. The majority of the respondents, namely 34 people, attend the gym. Fitness is also popular among the respondents, 26 of the surveyed people are engaged in it. They sometimes dance, perform sports dance moves – 11 of the respondents. This is due to the fact that most of the respondents are female. Of the 50 survey participants, 8 people are involved in athletics. 7 male respondents are involved in football. Only 3 people out of the respondents are engaged in gymnastics. Volleyball and basketball are not very popular among the respondents, they are practiced by 3 people each. Aerobics is also not popular – only 2 people do it, and it is girls. Also note that each sport determines the presence in the wardrobe of clothes. So, it was found out during the marketing research conducted by us that the majority of respondents, namely young people, are engaged in sports, and this is obvious, since everyone wants to keep fit, and especially in their youth. Many of them exercise several times a week, that is, quite often. The surveyed people mostly buy sports clothes and shoes on their own, both for training and for everyday life. The respondents spend mainly 3-5 thousand rubles on these purchases. The surveyed respondents mostly like to buy sportswear and shoes in shopping malls or special sports stores. As it turned out, the brands that are the most popular among the surveyed youth are Nike and Reebok. 19 CHAPTER 3. THE MAIN SAMPLING PROBLEMS FOR ONLINE SURVEYS Internet research has become an integral part of modern scientific work. They allow you to conduct research using online questionnaires, data analysis from social networks and other digital sources. However, for all their advantages, Internet research has a number of specific sampling problems. A number of significant limitations and disadvantages that cannot be ignored do not allow online research to completely displace traditional ones. One of the main sampling problems in Internet research is the problem of unrepresentativeness of the sample. Unlike traditional sampling methods, where researchers have the ability to control the composition of the sample, this is much more difficult in online research. The Internet has a huge variety of users, which can lead to underestimation or overestimation of certain groups of the population. For example, social media users may be younger and more educated than the general population, which may distort the results of the study. The main problem is that the sample of Internet users is not representative of the population of the country or even the region. The opinions of Internet users will differ from the opinions of the rest of the population. In addition, volunteers participate in the online study - the most active and curious Internet users. Such self-Selection makes it difficult to control the correspondence between the sample and the general population. Even if we limit the general population to the Internet audience only, the sample from it may be biased towards the audience of those sites whose visitors were invited to the survey. The composition of the audience of individual Internet resources is constantly changing, and the frequent change of E-mail creates the same problem as changing the address of residence or phone number - the inability to identify an Internet user as a unique respondent. Registration by multiple E-mails allows an Internet user to repeatedly fill out the same questionnaire, thereby affecting the distribution of responses. The probability of deliberate misinformation increases when a financial 20 reward is due for participating in the survey. If the respondent is interested in increasing their chances of winning or simply wants to «improve» the result of the survey (testing), they try to give a socially expected answer. More often than others, such answers are given by «trained» respondents using «low-cost» questionnaire filling strategies. Since Network users voluntarily provide all information about themselves, it is problematic to assess the reliability of socio-demographic data of potential respondents, their motivation, conscientiousness, and sincerity of answers. In addition, Internet users can give false answers by choosing them randomly, considering the survey as a game, entertainment. The desire to reduce the time required for data collection has negative consequences. If, after the expiration of the time allotted for sending invitations, respondents come via links to a closed survey, this will reduce their loyalty in the future. In addition, the sample may shift towards more active respondents. Therefore, even with small online samples, the field stage should be at least 3-4 days, and for large samples, especially with multiple quotas, at least 6-7 days. Online survey software can be «hacked» by computer hackers or subjected to a DDoS attack (Distributed Denial of Service). For example, if competitors are interested in distorting the results of the study or disrupting it [18, p. 24]. Internet users are not inclined to participate in lengthy interviews. Short questionnaires on Websites usually contain 1-3 questions, long ones - no more than 2025 questions. Although Web Panel participants who have agreed to receive survey invitations can answer 50 or more questionnaire questions, it is impossible to get the respondent to answer all the questions. An online survey can be considered successful, which is fully completed by 70-80% of those who started responding. As in a regular questionnaire, the respondent may misunderstand the meaning of some of the online questionnaire questions and respond inadequately to them, and the researcher may make mistakes in interpreting his answers, especially those received in writing. Surveys conducted by foreign companies sometimes sin by carelessness of design, poor Russian 6 language, excessive length. Foreign researchers sometimes have 21 a poor understanding of the specifics of the Russian audience, trying to make the questionnaire universal for any country. The same Web page may be displayed differently by different Internet browsers, so that the respondent has a wrong idea about the actual size and properties of the graphic images presented to him, photographs of objects. The respondent's perception of text and graphic (color, brightness, configuration) material may be influenced by the type of monitor, sound and video cards, and screen resolution [17, p. 62]. Another sampling problem in Internet research is the problem of selection. Internet research can only attract users who have access to the Internet and know how to use online technologies. This may exclude certain population groups from the sample, such as the elderly, low-income families, or residents of remote regions. Thus, the results of the study may be unreliable and inadequate. In addition, the problem of sampling in Internet research is the problem of selfselection of study participants. Unlike traditional methods, where the researcher chooses the participants of the study himself, on the Internet, participants can independently decide whether to participate in it or not. This can lead to distortion of the results of the study, as participants may be more interested in certain issues or have their own subjective opinion. The above factors, taken together, distort online research data. Since their verification is difficult, it is necessary to carefully clean the received array of responses and cull all suspicious respondents from it. Thus, sampling problems in Internet research are a serious challenge for researchers. To improve the quality and reliability of the research results, it is necessary to carefully consider the sample, taking into account the characteristics of Internet users, control the selection process and strive for maximum representativeness of the sample. 22 CONCLUSION Today, interest in online research is constantly growing all over the world, which makes it possible to reach a large and at the same time an increasing part of the inhabitants of different countries. This trend is visible not only abroad, but also in the Russian Federation, where more and more organizations, together with traditional survey methods, include Internet surveys among the services provided. One of the main issues in the implementation of an online survey is the formation of a sample, that is, the allocation of the contact audience on which the research will be conducted. Significant factors in this case are the representativeness of the sample. The formation of a sample for conducting an online survey can be of the following types: spontaneous; selected / eliminated; recruited / panel. Spontaneous (the sampling contour is formed by registered and/or unregistered site visitors who have shown interest in participating in the survey). When organizing the results, it should be taken into account that the most active users usually take part in the study. Selected/eliminated (created by the method of mailing invitations to site visitors selected with a quota assignment based on characteristics related to research tasks; response ranges from 30% to 50%). For randomization, the «pop-up» technique can be used – a window with an invitation to participate in the study is shown in front of each nth visitor of the site. Recruited/panel (created on the basis of a constantly updated structured set of data from potential respondents). The WEB panel is methodologically the most relevant way to engage in online surveys. Due to the available socio-demographic information about the respondents, the researcher can make the samples necessary for each specific study. The most preferred and freed from the problems typical of the Internet seems to be just the last, panel selection. 23 The problems are sample bias (lack of representativeness, spontaneity of the sample, audience coverage, dynamism, instability of the social space on the Internet); misinformation of the researcher (repeated participation in the survey, lack of information about the data on the general population; deliberate distortion of data, the likelihood of hostile actions); technical limitations (short length of the questionnaire, control along the way filling, communication problems, individual system parameters). Regarding specific sampling problems, using the example of analyzing the loyalty program of the Moscow Museum of Modern Art using Internet questions, bias and unrepresentativeness can be distinguished, it is believed that the age division reflected in the survey is very different from real museum visitors, which strongly affects the results of other questions, it is assumed that there are fewer young visitors, which requires additional research. The age bias could greatly affect the results of the responses, so, for example, according to the experience of marketers, loyalty programs are more relevant for older visitors. Thus, it is known that the study of the loyalty program of the Moscow Museum of Modern Art using Internet questions requires improvement in the formation of a sample or should switch to a non-linear format. The problems are significant enough to cast doubt on the results of the study. Thus, all the objectives of the sample research in the Internet survey, which were set in the introduction, were achieved. 24 BIBLIOGRAPHY 1. Chernykh V. V.
