bro i have a question. in some questions, we take a^2 for the variance while sometimes the ms just takes a. how do we identify that

being a hindu living in a three-generational household means a mandatory pooja (prayer) room with statues and frames of gods; I think I might just put up Jacob's picture there:)

Variance of any number is just zero "var(-3) = 0", in Q3 I'm taking the variance of variables that's why they don't disappear. I think this is what you're asking about.
