CompTIA DataX (DY0-001) — Question 36

A data scientist observes findings that indicate that as electrical grids in a country become more and more connected over time, the frequency of brownouts and blackouts in total decrease, and the frequency of major brownouts and blackouts increase. Which of the following distribution metrics could best be identified?

Answer options

• A. Scale axis magnitudes
• B. Kurtosis
• C. Skewness
• D. Normality

Correct answer: B

Explanation

Kurtosis measures the 'tailedness' of a distribution, which is relevant here since the frequency of major brownouts and blackouts increasing suggests a higher peak and heavier tails in the distribution. Scale axis magnitudes, skewness, and normality do not effectively capture the change in the distribution's tail behavior that is indicated by the observed findings.
