what does Szz mean also I don't get why the variance value is 80.55/31. <@&791435371564892232>

I assume S is sum of squares?

#

or maybe sum of (xi - xbar)^2 actually

#

but then isnt the mean^2 ignored?

#

i change my mind to this

lilac spade Nov 26, 2023, 9:31 PM

#

dont know what that is

thorny crater Nov 26, 2023, 9:31 PM

#

just a type of sum thing

#

#

i wont try to understand that rn cuz it will become too complicated

#

but i am guessing Szz is = sum of squares - mean

or variance....
