Quizplus · Accepted Answer

Varp should be used to find the variance of a population since it divides by the total number of values in the population, while Var divides by the sample size (n-1) to obtain an unbiased estimate of the population variance. StDev and StDevp are used to find the standard deviation of a sample and population, respectively.
