B)the calculation in the numerator is different
C)the calculation in the denominator is different
D)both B and C

Both the numerator and denominator formulas differ between the sample variance and population variance. In the numerator, the sample variance formula divides by n-1 instead of n, while in the denominator, the sample variance formula uses degrees of freedom of n-1 instead of n. Additionally, the population variance formula uses a computation for sum of squares (SS), while the sample variance formula does not.
