    You know what? I’m in mathematical statistics 2 right now and both of my math stats professors brushed over variance, but I wonder why they never went over this particular fundamental! I thank this guy so much, because now I have a better understanding.

    Sir, two formulas of variance are given one is having n-1 in denominator, while the other one is having only n in denominator.Now, how can we decide that we have to use which formula.

    • @shinwakira3533
      @shinwakira3533 2 ปีที่แล้ว +1

      I'm not sure I'm right but the one where the denominator is only N is for the formula of x bar while the one with N-1 is for the Variance itself
