Frequently Asked Questions
Standard error (SE) measures the precision of a sample mean estimate of a population mean. It is the standard deviation of the sampling distribution of the mean.
Standard error is calculated as the sample standard deviation divided by the square root of the sample size: SE = s / √n.
A smaller standard error indicates a more precise estimate of the population mean. The threshold depends on the context and the scale of the data.
