Which of the following measures would be useful for commenting upon the degree of asymmetry in a statistical distribution?
ACentral tendency
BDispersion
CKurtosis
DSkewness ✓ Correct
Correct answer: (D) Skewness — Skewness measures the degree of asymmetry in a distribution, so the answer is skewness.
Explanation
★Skewness measures the degree of asymmetry in a distribution, so the answer is skewness.
★Skewness shows whether a distribution leans to the left or the right of its centre.
★A symmetrical curve has zero skewness, while a lopsided one is positively or negatively skewed.
★Central tendency gives the centre of data, such as mean or median.
★Dispersion measures the spread, such as range or standard deviation.
★Kurtosis measures the peakedness or flatness of a distribution, not its asymmetry.
