The standard deviation of a distribution of means is a. the square root of the variance of the distribution of means b. calculated by subtracting the variance from the sample mean and taking the square root c. the population variance divided by the N in each sample d. the same as the square root of the sample varianceMay 18, 2012 What's the relationship between the standard error (which is the standard deviation of sampling means) and the standard deviation of the population? Why divided by error divided by standard deviation

In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion
