    The variance of the sampling distribution of the mean is the population variance divided by N, the sample size

    Step-by-step explanation: The variance of the sampling distribution of the mean is the population variance divided by N, the sample size (the number of scores used to compute a mean)

    Population variance refers to the value of variance that is calculated from population data, and sample variance is the variance calculated from sample data. As a result both variance and standard deviation derived from sample data are more than those found out from population data
