Question

Quizplus · Accepted Answer

Skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable. Since nominal level data categorize variables without a natural order or ranking, you cannot determine the skewness of its distribution. Skewness calculations require interval or ratio level data where mathematical operations such as subtraction and division are meaningful.
