A sample of n = 25 scores is selected from a population with a variance of σ² = 16,and the variance is computed for the sample using n - 1.The sample variance probably will be smaller than 16.

Question

When using n - 1 (Bessel's correction) to compute sample variance, it corrects the bias in the estimation of the population variance from a sample, often leading to a larger, not smaller, estimate of variance compared to using n, especially for small sample sizes.
