Quizplus · Accepted Answer

The total number of students in the sample who visited campus bars on the weekend before the final exam week is a count of individuals, which is a characteristic of a discrete random variable. A parameter is a characteristic of a population, not a sample. A continuous random variable takes on a range of values, not just specific counts. A categorical random variable represents categories or groups, but the total number of students visiting campus bars is not a category or group.
