Answer:
Sample
Population
Explanation:
When doing research, we have to consider our sample and our population.
The population is a set that contains all members of a specified group, to which the results of the study will generalize.
On the other hand, a sample is a subset of the population. In other words, it's part of the original population and therefore, the size of a sample is always less than the size of the population. The sample is the part of the population we're going to work with in a study/research/poll, etc.
Amy is conducting a survey among young adults as part of her master's thesis, she distributes 200 randomly selected students enrolled in the introductory psychology courses at her university.
This 200 students constitute Amy's sample (since it's the subset that is going to be studied). The people to whom she assumes her results will generalize are termed the population (since she will generalize the results to a much larger group)
