Webb14 feb. 2024 · When you take samples from a population and calculate the means of the samples, these means will be arranged into a distribution around the true population mean. The standard deviation of this distribution of sampling WebbIn more general, the standard error (SE) along with sample mean is used to estimate the approximate confidence intervals for the mean. It is also known as standard error of mean or measurement often denoted by SE, SEM or SE. The estimation with lower SE indicates that it has more precise measurement.

Webb29 apr. 2024 · The SEM, a measure of the error in the scores that is not due to true changes, was calculated by dividing the standard deviation of the difference between test and retest scores (SDdiff) by √2.
