And then there's 43 times that I sampled a 1 in my sample population. 43 times I sampled a 1. And the 1 is 1 minus 0.43 away from the mean, because that is the mean. And I want to square that distance. And then I don't want to just divide it by n. I don't want to just divide it by 100. Remember, I'm trying to estimate the true population mean in order for this to be the best estimator of that. And I gave you an intuition of why many, many videos ago.
