Calculating sample variance requires a slight modification in the formula as compared to calculate in population variance. Why? a) the population parameter is equal to the sample statistic b) the sample variability is too difficult to measure directly c) samples have systematically more variability than the populations from which they are drawn d) samples have systematically less variability than the populations from which they are drawn
