Question

for each part below, indicate whether the variable is a quantitative or a categorical (qualitative) variable.

(a) price (in dollars) of a shirt on the clearance rack

(b) university in which a student is enrolled

(c) mothers occupation

(d) medal won in a recent race (gold, silver, bronze, or none)

Explanation:

• (a) Price (in dollars) of a shirt on the clearance rack: Quantitative variables represent numerical measurements. Since price is measured in dollars (a numerical value), it is a quantitative variable.
• (b) University in which a student is enrolled: Categorical variables represent non - numerical categories or groups. Different universities are distinct categories, so it is a categorical variable.
• (c) Mother’s occupation: Occupations are non - numerical categories (e.g., teacher, doctor, etc.), so it is a categorical variable.
• (d) Medal won in a recent race (gold, silver, bronze, or none): These are non - numerical categories, so it is a categorical variable.

Answer:

(a) Quantitative
(b) Categorical
(c) Categorical
(d) Categorical
