Quizplus · Accepted Answer

The standard deviation of all possible sample means is called the standard error of the mean (SEM). This is a measure of how much the sample mean deviates from the true population mean. The standard error of proportion (A) is a measure of how much the proportion in a sample deviates from the proportion in the population. The mean deviation (C) is a measure of how far the observations in a sample are from the sample mean, but it does not take into account the size of the sample. Central variation (D) is not a commonly used statistical term.
