d. A statistics student creates a survey and presents it to fellow statistics students.

Accepted Answer

All right, hello, everyone. So this question is asking us to identify the term that best describes the type of sample in the following example. A psychology student designs a questionnaire and distributes it only to other psychology students at their university. Option A in the multiple choice says systematic sampling. B says convenient sampling. C says stratified sampling. D says cluster sampling. And option E says simple random sample. So let's start by understanding the different types of sampling. That are listed here as the multiple choice options. Starting off with systematic sampling, which, if you recall, describes selecting every nth individual from a greater list. So if, for example, you had a group of 100 people to choose from, selecting every 5th person of those 100 would be an example of systematic sampling. Now, convenient sampling, on the other hand, is all about ease of access. In other words, choosing subjects from those that would be most. Easily accessible. An example of this would be, for example, going to a public place. And looking for participants among the people that are already in that public space. Now, for stratified sampling, that's option C, the keyword here is strata. Which is a word to describe subgroups. So in the case of stratified sampling, you have a greater population that you want to study. That population is first divided into multiple subgroups or strata. And then Participants are sampled from each subgroup. Now cluster sampling. Involves selecting whole groups. As opposed to picking individuals for the study. And last but not least we have the simple random sample. Where every individual has an equal chance of getting selected for the study. So now let's go back to the scenario. And in this particular case, we have a psychology student that is selecting other psychology students at their university for the questionnaire to be filled up. So Notice the Notice the specificity of the population that's being used here. It would be more difficult for the student to go up to other students in different departments for the questionnaire, right, for them to fill out the questionnaire. Instead, the student chooses to distribute the questionnaire only to other psychology students that the students themselves are more likely to come across. As everybody would be studying the same thing. Right, so the key word here is ease of access. Because the sample consists only of psychology students, you're not representing a larger population. This means that convenience sampling is most appropriate, making option B the correct answer. And there you have it. So with that being said, thank you so very much for watching, and I hope you found this helpful.
