I can do all that, but other calculator versions have the ability to calculate the SD of a frequency distribution in sets and such. How do i do that on this calculator, or in a mlre specific manner, the second edition of it?

How about the sum of the product? Or the (sum. XY) ?

Why do i have different a symbol on the standard deviation and Population standard deviation? It is the same right? It looks like “x6n-1” and “x6n”

@HDCalcs 3 года назад

Are you getting the same results for "x6n-1" as the examples sample standard deviation (Sx) 23.80476...? It looks like the "x6n-1" might be an alternate symbol for that.
