Why we divide by n - 1 in variance

In this video, we discuss why we use n-1 in sample variance instead of n. We explain the concept of sample variance and how it is used to estimate the population variance. We also discuss why using n in the denominator leads to a biased estimate of the population variance and how using n-1 instead corrects for this bias. #statistics #datascience #samplevariance #populationvariance #mathematics #bias #estimation. | The Statisticians
