Accepted Answer

All right, hello, everyone. So this question says, in a survey of 25,000 college students, 62% reported that they spend more than 3 hours daily on their smartphones. Identify the sample and the population. So first, let's take a moment to understand the difference between a sample used in a study versus the population. And I'm actually going to go ahead and start with the population first. Now, Oftentimes the purpose of a study is to understand. More about a certain group of people, right? So in this case, the population. Involves the larger group of people. Of interest, so to speak. And what I mean by that is that the population includes all individuals that the researcher wants to study as they are designing their survey, or their study as a whole. Now, the problem is that oftentimes any given population is simply too large for one study to address fully. So therefore, the most practical thing for researchers to do. is to use a subset of a given population to conduct their study, and then use that data from the subset to draw conclusions about the greater population. So the sample, therefore, Is the subset of the population that is actually included in the survey. Or included in the study in general. So, in this particular case, the given study is about the smartphone habits of college students, which means that the population, the group of interest is college students. But once again, the population. It is too big for only one study to address fully, right? And so the sample is a subset of the population. So in this case, the sample. Would be the 25,000 college students that were actually surveyed. So, therefore, our answer is going to be option D in the multiple choice. Because the sample is the 25,000 surveyed students, whereas the population is all college students. And so with that being said, thank you so very much for watching, and I hope you found this helpful.
