The key difference between sample variance and population variance lies in the denominator of their formulas. For population variance, the denominator is N (the size of the population), while for sample variance, it is n-1 (the size of the sample minus one). This adjustment, known as Bessel's correction, is used to correct the bias in the estimation of the population variance from a sample.
