sample standard deviation for the following scores: -8, 4, -7, 6, 8, 5, -7, -9, -2, 0
I have attached bartlby answers from this website. I was wondering why do they not subtract 10-1 on the bottom of the standard variance equation? isn’t that part of the formula? Am I missing something? Thank you! If this is incorrect, can you give proper answer?
