The standard error (SE) is a statistical measure that quantifies the variability or precision of a sample mean in relation to the true population mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size. A smaller standard error indicates more reliable estimates of the population mean, while a larger SE suggests greater variability and less confidence in the estimate. SE is often used in inferential statistics to construct confidence intervals and conduct hypothesis tests.

How does sample size affect the size of your standard error?
