WebDenoted by SK, it is calculated as follows: SK = 3 ( m - m ) / s for a population. = 3 ( - ) / s for a sample. For a perfectly symmetric distribution, the mean and median will have the same value, and SK will have the value of 0. A distribution that is skewed to the right will have a mean that is larger than the median, and thus SK will have a ...
