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

jim_thompson5910 · Answer

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

jim_thompson5910 · Answer

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