Calculates the skewness of a distribution using the population, i.e. the possible outcomes, of a random variable. The sequence shall contain three numbers at least.

This function is part of the Open Document Format for Office Applications (OpenDocument) standard Version 1.2. (ISO/IEC 26300:2-2015)

### Fakkeenyawwan

SKEWP(2;3;1;6;8;5) returns 0.2828158928

SKEWP(A1:A6) returns 0.2828158928, when the range A1:A6 contains {2;3;1;6;8;5}

SKEWP(Number1; Number2) always returns zero, if Number1 and Number2 results in two numbers.

SKEWP(Number1) returns Err:502 (Invalid argument) if Number1 results in one number, because SKEWP cannot be calculated with one value.
