1 PRACTICAL RESEARCH 2 (QUANTITATIVE) First Quarter: Week 1 Name: Section: _ _ Grade Level: Date: LEARNING ACTIVITY SHEET Day 1: DESCRIBING QUANTITATIVE RESEARCH Background Information You learned that there are two general methodologies in research, qualitative and quantitative. You learned the characteristics, strengths, and weaknesses, the types of qualitative research. In like manner, let us study quantitative research. Babbie (2010) defines quantitative research as either descriptive or experimental because subjects are measured once or before and after. Its data are gathered via structured instruments, and the result is based on large sample sizes that are representative of the population. This methodology aims to classify features, count them, and construct statistical models in an attempt to explain what is observed. The methods used in this research are replicable, which starts from a clearly defined research question to which objective answers are sought. In essence, quantitative research is mainly collecting numerical data to explain a phenomenon. The quantitative paradigm (Aliaga and Anderson 2000) may be further described by answering the following questions: Question Answer What is the nature of reality? Reality is objective, singular, and separate from the researcher. What is the relationship of the researcher to the subject of research? The researcher is independent of the subject of research. What is the role of values? Research is value-free and unbiased. What is the language of research? Formal, based on set definitions, impersonal voice and uses accepted quantitative words. What is the process of research? Deductive process Cause and effect Static design-categories isolated before the study Generalizations leading to prediction, explanation, and understanding Accurate reliable through validity and reliability. Learning Competency with Code: Describes characteristics, strength, weaknesses, and kinds of quantitative research (CS_RS12-Ia-c-1) Exercise 1: Modified True or False. Write the word TRUE if the statement is correct. Otherwise, underline the word or phrase that makes the sentence FALSE and write the correct one on the space provided. 1. Quantitative research is either descriptive or experimental, where subjects are measured once or by before and after. 2. Quantitative research is interested not only in examining the phenomenon but also its causes. 3. Data on quantitative research are gathered through an unstructured interview. 4. Quantitative research deals with data that are ungeneralizable to the population. 5. Quantitative data is collecting data that are in the forms of words or phrases. 6. For quantitative research, the reality is subjective, singular, and is separated from the researcher. 7. The deductive process is used in quantitative research. 8. The language used in quantitative research is said to be formal, based on set definitions voice, and uses accepted quantitative words. 9. Generalizations of qualitative data should lead to prediction, explanation, and understanding. 10. Research instruments in quantitative research go through validity and reliability testing. DAY 2: STRENGTHS AND WEAKNESSES OF QUANTITATIVE RESEARCH Background Information Just like qualitative research, the quantitative methodology also has its strengths and weaknesses, as discussed by Melegrito and Diana (2016, 31-35). So, let us talk about its strengths. The quantitative methodology is robust in terms of data analysis. It produces descriptive data/terms which can be formed into graphical models for making interpretation easier. It provides numerical data that are derived from statistical tests, whether descriptive or inferential statistics. It helps in making declarations on specific data. Important facts such as preference trends, differences between groups, and demographics are derived from statistical analysis, which can only be done in quantitative research. On the other hand, it also has its limitations. One of them is that there is a need to ensure that measures are valid and reliable. Otherwise, it will not be easy to interpret its data. Another limitation is the data deficiency. You have learned that quantitative research works on data that is generalizable to a population. It means there is a need to have large samples of sources of data for it to become reliable. Otherwise, it may lead to critical errors. Lastly, overreliance to p-value and sample size also poses limitations to quantitative research. P-value (calculated probability) refers to the probability of finding the observed or more extreme results when Ho (Null Hypothesis) is true. It is also described in terms of rejecting Ho when it is true but not a direct probability of this state. Sample size (n) refers to the number of observations (in research: the number of respondents or participants derived from the population). For this reason, a p-value is possible to be manipulated by the sample size to have a statistical power (SP – a study has the probability of detecting an effect of a certain size). When a sample is underpowered due to the small size, there is a high tendency not to realize a statistical significance. Hence, the sample size must be increased if statistical significance is scarce with meaning. Statistical significance communicates with the researcher if the results are valid. Effect size expresses how much results carry some weight or if they make a difference. Ex. “If you were examining whether adding a feature would increase a product’s value. You could have a statistically significant finding, but the magnitude of the increase in value might be minimal- say a few cents. In contrast, a meaningful effect size might result in an increase in the value of PHP 50 per unit. If you can achieve statistical significance with a small “n,” the effect is reasonably substantial. Hence, both statistical significance and effect size must be both put into account when interpreting data.” Learning Competency with Code: Describes characteristics, strength, weaknesses, and kinds of quantitative research (CS_RS12-Ia-c-1) Exercise 2: Write the Strengths and Limitations of Quantitative Research on the correspondings spaces below.

Adapted from: National Council of Teachers of Teachers (NCTE) 2004) DAY 3: KINDS OF QUANTITATIVE RESEARCH Background Information: In your qualitative research, you learned that different types of qualitative research are used based on the nature of the study you wish to undertake. In the same manner, quantitative research all offers different kinds of designs that are used depending on the objective or topic of your study. Let us tackle them one by one. Descriptive Research. Anastas (1999) explained that “this research answers the questions 4W and H (What, Where, When, Who, and How) except why. These questions are which are linked to the research questions” (Melegrito and Mendoza 2016, 23). It does not answer “why” because it does not seek to explain why certain things happen. It is only applied to describe what exists and gather information on the current status of a particular. Survey Research. Bryman (2008) explained that this research design is intended to acquire information from people. It aims to gather data concerning the predominance, distribution, and interrelations of the variables within an identified group. It aims to gather evidence of people’s knowledge, opinions, attitudes, and values on various issues and concerns. Correlational Research. This research design is based on pairs of measures or scores of a single sample. It indicates the strengths of the relationship between two variables that embody the characteristics or performances of a group (Melegrito and Mendoza 2016, 24-25). The correlation ranges are as follows: 1.00 to + 1.00 0 and +1.00 0 and – 1.00 0 Correlation Range Positive Correlation Negative Correlation No Correlation You have to take note that in correlation research, it is not the positive or negative relationship that matters. Instead, it is the size of the correlation between two variables. Causal Comparative/Quasi-Experimental. Gay (1996) considers this design as descriptive, for it describes existing conditions. Still, it endeavors to find the causes of the existing phenomena. Hence, this design is about proving the cause and effect relationships that descriptive and correlational studies do not ascertain. It also sometimes likened to experimental research because it generates cause and effect relationships. However, it lacks manipulation of the independent variable. That is why this research is also sometimes likened to correlation. (True) Experimental Research. In this study, the researcher is authorized to control the situation and manipulates the Independent Variable (IV) to detect its influence on the Dependent Variable (DV). This design attempts to identify the cause and effect relationships between variables. In social science, many IVs cannot be manipulated (Bryman 2008). Hence, you must be cautious with experimental design because it is artificial and may not be generalized well to the real world. It is because artificial settings may alter the behavior of the participants. Examples: Type of Quantitative Research 1. Descriptive Research 2. Survey Research 3. Correlation Research 4.

Gutierrez (2020) mentioned that “research is of great value to people. Through research, the quality of life man has improved from conventional to modern. It has made life richer and more meaningful. Through research, people have found ways to augment their income and alleviate poverty.” Quantitative research, because of its emphasis on proof, rather than discovery, has been widely used in most disciplines (Prieto, Naval and Carey 2017). Whether it is in the field of Medicine, Dentistry, Education, Sports, Social Sciences, Nursing and many more. Quantitative Research Across Discipline Qualitative research is oriented toward analyzing specific evidences in temporal and local particularity. It starts with the respondents’ perspectives, expressions, and activities in their local context. In this case, qualitative research is important across many fields of inquiry because it is designed for social sciences, psychology, and other fields. With this, qualitative research would verify or validate the tendencies, transform it into research programs, and maintain the necessary changes toward its objectives and tasks. What discipline am I? Careful analysis and comprehension of specific research titles may give hints on the kind of discipline it will focus. Example: Medicinal Effects of Guava Leaves (Quantitative Medicine/Medical Education) Learning Competency with code Illustrates the Importance of Qualitative Research Across Fields (CS_RS12-Ia-c-2).

The following are common variables in research, i.e., age, sex, gender, education, income, marital status, and occupation. Natures of Variables/Data 1. Nominal Variables - are variables that have two or more categories but which do not have an intrinsic order. Examples: Biological Sex (Boy and Girl), Gender (Male, Female, etc.), Political Affiliations (Liberal, Democratic, etc.), Basketball Fan Affiliation (Alaska Aces, TnT Katropa, etc.). 2. Ordinal Variables - are variables that have two or more categories, just like nominal variables only the categories can also be ordered or ranked. Examples: Educational Level (Kinder, Grade 1, etc.), Age Brackets (Children, Infant, etc.), Classroom Ranking, etc. 3. Interval Variables - are variables for which their central characteristic is that they can be measured along a continuum and they have a numerical value. Examples: Temperature, Individual’s Net Worth, etc. 4. Ratio Variables - are interval variables, but with the added condition that 0 (zero) of the measurement indicates that there is none of that variable. Examples: Height, Mass, Distance, etc. Kinds of Variables 1. Independent Variables – are variables the experimenter changes or controls and is assumed to have a direct effect on the dependent variable (Saul 2019). Example: Title “Effects of Age on the Quarterly Grades of Senior High School Students”, Dependent Variable (Quarterly Grades), Independent Variable (Age). 2. Dependent Variables – are variable being tested and measured in an experiment and is 'dependent' on the independent variable (Saul 2019). Example: Title “Effects of Age on the Quarterly Grades of Senior High School Students”, Dependent Variable (Quarterly Grades), Independent Variable (Age). 3. Intervening/Mediating Variables - variable that helps explain the relationship between two variables. Example: Title “Effects of Age on the Quarterly Grades of Senior High School Students”, Dependent Variable (Quarterly Grades), Independent Variable (Age), Possible Intervening Variable (Age Bracket). 4. Control Variables – are variables which the researcher holds constant (controls) during an experiment (Helmenstine 2020). Example: Title “The Relationship of Content-Based Integration Activities to Quarterly Grades of Senior High School Students”, Control Variable (Grades of Students in a Control Group that does not facilitate Content-Based Integration Activities), Experimental Variable (Grades of Students in a Experimental Group that facilitates Content-Based Integration Activities) 5. Confounding Variables – are variables, other than the independent variable that you're interested in, that may affect the dependent variable (McDonald 2014). Example: Title “Effects of Age on the Quarterly Grades of Senior High School Students”, Dependent Variable (Quarterly Grades), Independent Variable (Age), Possible Confounding Variable (Family Income, Social Status, etc.).

Adapted from: National Council of Teachers of Teachers (NCTE) 2004) Answer Key Activity 1 (Kinds of Variables) 1. Independent variables affect dependent variables. Independent variables are the ones the controls the latter which is the one being tested. 2. These are variables coming from a control group that is the basis for comparing the changes that happen to the experimental variables. 3. These are variables that are affecting the dependent variable aside from the independent variable that may affect the results of a study. 4. Demographics of the Asian subjects of Vaccine ABC against Pathogen XYZ. The effectiveness of a vaccine varies from everyone who is affected of a certain pathogen. Age, gender, lifestyle, etc. which are under demographics of a population can be a big factor in the effectiveness of a certain vaccine. 5. Effectiveness of Vaccine ABC. The effectiveness of a vaccine may change depending on the demographics of the population who are going to take the dosage of the vaccine. Prepared by Vito Dominic D.

Research is as good as its findings because it answers or solves real-world phenomena. It typically calls to “mind mathematical formulas that describe the everexpanding the natural phenomena, complex theorems, liquids in test tubes, endless experiments to explain phenomena, human behavior, and the like” (Prieto, Naval and Carey 2017, 27). Research affects us and the society that we live in each day of our lives. The way we experience relationships, how we perceive the world, how society is governed, and a lot more is influenced by the expanding knowledge that we produce. In other words, we need research to make sense of our world, and to answer certain phenomena of different disciplines, corporations, government organizations, our field of specialization, and many more. Possible Research Topics Related to Daily Life Research must be innovative in nature; it must operate on areas between disciplines. Your research topic must be concerning your field of specialization or anything that might interest you. Is the Topic or Situation (Researchable or Not Researchable)? Topics or specific situations that are answerable by a simple inquiry process \NOT Researchable. If the topic cannot be answered by simple inquiry and needs further investigation and data analysis, then the topic is Researchable. Example: Poverty Alleviation, Unemployment etc. Learning Competency with code Designs research used in daily life (CS_RS12-Id-e-1). Exercise 1. Determine whether the following topic or situation is Researchable or NOT Researchable. Check the corresponding column of your answer. Topic/Situations Researchable NOT Researchable 1. A person wants to know the occupant of the hotel room 210. 2. A student wants to know the medicinal effects of guava. 3. Mr. Cruz wants to know the technique to make his television function efficiently. 4. A teacher wants to know the impact of ICT on student’s performance. 5. Mang Gustin wants to know the reason behind his decrease in sales in his sari-sari store. 6. A manager wants to know which form of advertising is useful in the business. 7. Mr. Rico wants to discover the impact of social networking on his students’ learning abilities. 8. Clara wants to know the study habits of his classmate. 9. Mr. Vien wants to know the reason behind the Grade 12 tardiness. 10. Group 2 wants to know the acceptability of their newly developed product. Exercises 2.
