Quizplus · Accepted Answer

Since the psychologist is measuring the attention span of undergraduates at a local university, they are collecting data from a subset of the entire population of college undergraduates in the United States. Therefore, the mean of these scores would be a statistic, not a parameter or population. A sample refers to the specific group of individuals who were measured in this study.
