The formula for estimating the SEM involves which two components?

Question

Quizplus · Accepted Answer

The formula for estimating the SEM involves the SD from a sample and the number of cases from that sample. This is because the SEM represents the standard deviation of the means of all possible samples of a given size, which is calculated using the SD of the sample and the square root of the sample size. The mean and SD from the population (option B) are not used because they are typically unknown. The SD from a sample and number of cases in the population (option C) are not both needed in the formula. The mean and SD from a sample (option A) are only used to calculate descriptive statistics, not the SEM.
