When comparing two groups of respondents, the researcher is typically interested in determining whether there is a statistically significant difference between the two groups. To do so, the researcher would conduct hypothesis testing where the null hypothesis would state that there is no difference between the two groups, and the alternate hypothesis would state that there is a difference between the two groups. In this context, the two groups are considered to be different populations, which are the groups that the researcher wishes to make inferences about based on the data collected. Thus, the best choice is A: different populations.
