Answer:
The correct answer to the question, to properly fill in the blanks, would be, B: sample; population. Thus, the entire question would be: ...The selected group served as the: sample of the college: population.
Explanation:
When doing research, one thing that is really important for researchers to do is to decide how their study sample will be formed, what characteristics the members of the group must have, its size, and how this group will become representative of a much bigger group. In research, selecting a group of members that will participate in a study is called a sample, a group that is big enough and that has enough of the characteristics present in a larger group, to become representative. The larger group from which the sample is selected, is called the population. In this case, the college campus students at large is the population, and from this population the researchers selected a much smaller group, but one that had enough characteristics to say that they were representative of the population. This group is the sample group.
