Question

1. determine whether the following variable is quantitative or categorical: number of students in a class

○ quantitative
○ categorical

Explanation:

To determine if a variable is quantitative or categorical, we analyze its nature. A quantitative variable is one that takes on numerical values representing quantities (like counts or measurements) and can be meaningfully added, subtracted, etc. The "number of students in a class" is a count (e.g., 20, 30 students), which is a numerical value representing a quantity. Categorical variables represent groups or categories (like colors, types of animals) and are not numerical in a quantitative sense. Since the number of students is a numerical quantity, it is quantitative.

Answer:

Quantitative
