18 janv. 2023It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set. The more spread the data, the larger the variance is in relation to the mean. Table of contents Variance vs. standard deviation Population vs. sample variance

So when we calculate our sample variance with this technique, which is the more mainstream technique– and it seems voodoo. Why are we dividing by n minus 1, wherein for a population variance we divide by n? But remember we’re trying to estimate the population variance. And it turns out that this is a better estimate.
