How to Calculate Standard Deviation (Guide)

With samples, we use n – 1 in the formula because using n would give us a biased estimate that consistently underestimates variability. The sample standard deviation would tend to be lower than the real standard deviation of the population. Reducing the sample n to n – 1 makes the standard deviation artificially large, giving you a conservative estimate of variability.
