Thanks for your best explanation

[@davidhill8163]

Fantastic, really clear explanation

[@dezertcammo]

My class always calculates standard deviation with (n-1) in the denominator. Can this calculator be adjusted to reflect that?

[@dezertcammo]

I found it. It’s listed as ‘SX’ in the result. Thanks for the video.
