WebThe purpose of using n-1 is so that our estimate is "unbiased" in the long run. What this means is that if we take a second sample, we'll get a different value of s². If we take a third sample, we'll get a third value of s², and so on. We use n-1 so that the average of all these values of s² is equal to σ².
