* You can also use a single array or a reference to an array instead of arguments separated by commas.
* If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
* This function can return large values when you have a large number of arguments.
* The Variance is the value returned from this function divided by the number of arguments.
* The value returned is often called the pooled standard deviation.
