The standard error is another name for the standard deviation of the sample mean (xbar) distribution

4. jim_thompson5910

Standard Error (SE): $\Large SE = \frac{\sigma}{\sqrt{n}}$ this is when sigma is known/given

5. jim_thompson5910

if sigma is unknown, but s is known, then $\Large SE = \frac{s}{\sqrt{n}}$
