Which of the following measures would be useful for commenting upon the degree of asymmetry in a statistical distribution?

Skewness measures the degree and direction of asymmetry in a statistical distribution.

Central tendency locates the centre of data but says nothing about its symmetry.

Dispersion measures the spread of values, not the lopsidedness of the curve.

Kurtosis describes the peakedness or flatness of a distribution, a separate shape property.

Positive skew stretches the right tail while negative skew stretches the left.

A perfectly symmetric distribution has a skewness value of zero.
