Web18 de jan. de 2024 · With samples, we use n – 1 in the formula because using n would give us a biased estimate that consistently underestimates variability. The sample variance would tend to be lower than the real variance of the population. Reducing the sample n to n – 1 makes the variance artificially large, giving you an unbiased estimate of variability: it …
