Which of the following statements about skewness and kurtosis is least accurate?

A) Positive values of kurtosis indicate a distribution that has fat tails.

B) Kurtosis is measured using deviations raised to the fourth power.

C) Values of relative skewness in excess of 0.5 in absolute value indicate large levels of skewness.

Positive values of kurtosis do not indicate a distribution that has fat tails. Positive values of excess kurtosis (kurtosis > 3) indicate fat tails.
