Inferential statistics:
A)Are limited to descriptively summarizing a study's data.

Question

Quizplus · Accepted Answer

Inferential statistics are used to make inferences about a larger population based on a sample. One of the main purposes is to assess the probability that any differences between groups can be accounted for by chance (sampling error) or whether they represent a true difference in the population. Therefore, option C is the correct answer. The other options are incorrect - A is incorrect because inferential statistics go beyond descriptive summaries, B is incorrect as inferential statistics are used to generalize beyond a sample, and D is incorrect as inferential statistics are used to make comparisons and test hypotheses, but not to assess equivalence.
