Standard Deviation versus the Standard Error of the Mean Both the standard deviation (SD) and the standard error of the mean (SEM) measure variability. However, after that initial similarity, they’re vastly different! Let’s start with the more familiar standard deviation. The calculation for t...

The weight of a group of women has a population mean of 121 pounds and a population standard deviation of 21 pounds. The distribution is right-skewed. Suppose a random sample is taken from 100 of these women's weights. What is the standard error for a sample mean taken fr...
SAMPLE STANDARD ERROR OF THE MEAN In the same way that we can estimate σ by s when we do not know σ, we can estimate σm by sm, using the standard deviation of a sample. The estimated SEM, sm, is the sample standard deviation divided by the square root of the sample size, or ...
