Webb24 apr. 2024 · The standard error of the mean, also known as the standard deviation of the mean, helps to determine the differences between more than one sample of information. The calculation accounts for variations that may be present in the data. The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution or an estimate of that standard deviation. If the statistic is the sample mean, it is called the standard error of the mean (SEM). The sampling distribution of a mean is generated by repeated sampling from th…
