CompTIA Data+ (DA0-001) — Question 59

A cereal manufacturer wants to determine whether the sugar content of its cereal has increased over the years. Which of the following is the appropriate descriptive statistic to use?

Answer options

• A. Frequency
• B. Percent change
• C. Variance
• D. Mean

Correct answer: D

Explanation

The mean is the best descriptive statistic to summarize the average sugar content over the years, allowing for comparison of changes. Frequency counts how often something occurs, percent change measures the relative difference, and variance assesses data spread, none of which directly indicate an increase in sugar content.
