Quizplus · Accepted Answer

The group selected is a sample because it represents a smaller portion of the larger population (in this case, all students entering the college library on a Tuesday afternoon). However, it is not a random sample because the selection process is based on a specific criteria (every 10th student) rather than a completely random selection. It is also not a quota sample because the selection process is not based on achieving specific proportions of certain characteristics, such as age or gender. Finally, a statistic refers to a numerical summary of a sample, whereas the group selected in this scenario is not yet summarized in any statistical way.
