Which of the following is true of the coefficient of skewness (CS)?
A) If the CS is positive, the distribution of values tails off to the left.
B) If the CS value is between 0.5 and 1, the skewness is considered to be moderate.
C) If the CS is closer to zero, the degree of skewness is considered to be high.
D) If the CS value is between -0.5 and -1, the skewness is considered negligible.

The coefficient of skewness measures the degree of asymmetry in a distribution. If the CS is positive, the distribution tails off to the right. If the CS is negative, the distribution tails off to the left. A CS value between 0.5 and 1 indicates moderate skewness. A CS value closer to zero indicates a lower degree of skewness or symmetry. CS values between -0.5 and -1 indicate negligible skewness. Therefore, B is the correct choice as it correctly describes the moderate degree of skewness.
