Quizplus · Accepted Answer

The standard deviation of all possible values is called the standard deviation of the population. However, when we have a sample of the population, the standard deviation of the sample is calculated, which is an estimate of the standard deviation of the population. The standard error of the mean is the standard deviation of the sample mean, which is a measure of how much the sample means vary from the true population mean. Therefore, the best choice is B, which correctly refers to the standard deviation of the mean.
