Dear all, My sincere apologies about a small error I made in the video. At 19:04, the formula for variance would include division by (n-1), not n. This is the formula for sample variance. If we do the calculation for population variance (the entire dataset of individuals from which a sample is drawn), then we would divide it by n. Please note the correction.
