standard error
Estimate's typical deviation
Standard error is a statistical measure of how much a sample statistic (like a mean) is likely to vary from the true population value.
A smaller standard error indicates the sample estimate is more precise.
Often abbreviated SE or SEM (standard error of the mean).
The standard error decreased as sample size increased.
