To find out which of the following is a categorical variable.
Answer to Problem AP4.7CPT
Option (d) is the correct option.
Explanation of Solution
Categorical variable places the individual into a category, while a quantative variable is a numerical variable.
Thus, in option (a), it is quantitative variable because the weight takes on numerical values.
In option (b), it is a quantitative variable because the time takes on numerical values.
In option (c), it is a quantitative variable because the fuel efficiency takes on numerical value.
In option (d), it is a categorical variable because the brands are not numerical.
In option (e), it is a quantitative variable because the closing price takes on numerical values.
Thus, the option (d) is the correct option.
