How do researchers decide the sample size to use in a study? What are some issues that influence this decision?
What will be an ideal response?
Ans: Responses should include that the size is determined differently depending on the type of methodology and sampling procedure to be employed in a study. The purpose of the study also decides the sample size that is needed. Responses must include a discussion of probability and non-probability sampling. The main distinction between these two groups depends on the random selection of participants and the use of a sampling frame. In probability sampling types, participants are randomly selected and a sampling frame is often used. In non-probability sampling types, participants are often not randomly selected and a sampling frame may not be available.
