Question

Quizplus · Accepted Answer

Z-scores in a sampling distribution of means are in standard error units. This is because the standard error measures the standard deviation of the sampling distribution, which is the distribution of all possible sample means for a given population. Z-scores are calculated by subtracting the mean of the sampling distribution from a particular sample mean, and then dividing by the standard error of the sampling distribution. Therefore, z-scores represent the number of standard errors that a particular sample mean is from the mean of the sampling distribution.
