Samples of n = 4 scores are selected from a population.If the distribution of sample means has a standard error σ = 5 points,then the population from which the samples were obtained has a standard deviation of σ = 20.

Question

The standard error of the mean (σM) is calculated as the population standard deviation (σ) divided by the square root of the sample size (n), so if σM = 5 and n = 4, then σ = 5 * sqrt(4) = 10, not 20.
