If a set of points represent probability density, then the third central moment is the ___________.
skewness
The third central moment of a distribution measures the asymmetry of the probability density, which is known as skewness. Skewness indicates whether the data points are skewed to the left or right of the mean. Hence, the correct answer is option 1, "skewness."
