Population skewness

WebIn practice, we can estimate the skewness in the population by calculating skewness for a sample. For the sample, we cheat a little by assuming that the random variable is uniformly distributed, so the probability of each y_i in the sample is 1/n and the third, central, sample moment becomes 1/n times a simple summation over all (y_i —y_bar)³.
