Sample Size
Sample size refers to the size of the population or representatives which were
extracted from the population size (Omniconvert, 2023). Our sample size of 100
people is therefore a representation of the population to get a more in-depth
knowledge of alcoholism in the construction industry. Simple random method was
used to obtain data, whilst creating equal opportunity for anyone to be selected, for
its cost-effectiveness, selection to not be bias and time conveniency.
Data Collection Method
The strategies and procedures used to collect data for research purposes are known
as data collecting methods. Surveys, interviews, observations, focus groups, and
experiments are some of the data collection techniques (Bhat, 2019). For a method
that is not time consuming and costly we chose the survey questionnaire method, a
printed set of questions that are open-ended and allows for the elimination of being
bias. Open-ended questions are used due to the nature of qualitative research
(Hotjar.com, 2023) as the researcher should be more focused on the quality of the
feedback to collect qualitative information and learn more about users' attitudes,
feelings, and actions (Dube, 2019)
The process of data collection
The questionnaire was handed out and some emailed to selected respondents from
23rd April until 26 May 2023*. Major focused district was Johannesburg whilst texts
and mail was sent to respondents nearby provinces such as Mpumalanga, North
West and the Limpopo Province. Constructions were located randomly, and
participants were chosen randomly on their willingness to operate. Once completed
all questionnaire have been collected and received then can researchers begin
interpretating data.
Question Type
The use of open-ended question is that researchers can get a better understanding
of the research when participants are given freedom to speak honestly and truthfully
whilst remaining anonymous. Due to long distance, some questionnaires were filed
in closed space, but most done in open space for safety and security reasons.
