CompTIA Data+ (DA0-001) — Question 144

A feature can take certain values (A, B, C, D, E, and F) and represents a grade of students from a college. Which of the following variables does this describe?

Answer options

• A. Discrete variable
• B. Ordinal variable
• C. Numerical variable
• D. Continuous variable

Correct answer: B

Explanation

The correct answer is B, as an ordinal variable represents categories with a meaningful order, such as grades. The other options are incorrect because a discrete variable refers to countable values, a numerical variable indicates quantitative measures, and a continuous variable can take any value within a range.
