A) The computation of sum of squared deviations is the same for both samples and populations. 
B) Squaring each deviation ensures that negative deviations do not cancel out positive deviations. 
C) The sum of squared deviations is the numerator for both the sample variance and population variance formulas. Therefore, all of the above choices are correct.
