How to Calculate Standard Deviation using Casio fx-95 MS Calculator?

A

amanbhai

It maybe a very simple question for many.
I am using Casio Scientific calculator fx-95 MS.
My question is: I can do statistical calculations by using SD mode given.
but when I calculate standard deviation, I chose Xsigma (n-1) why not sigma n?
thanks

Hello amanbhai,

Sigma (n) = Population standard deviation.
Sigma (n-1) = Sample standard deviation.

Explanation: Standard Deviation.
