Calculating the Standard Error of Mean

The Statistics menu option Errors and differences > Standard error of mean computes the standard error, which is the standard deviation of the mean estimator based on all selected field quantities. For each selected quantity, a single result object is created. Each result object is a field vector that contains the standard error at each mesh position.

For quantity Y, number of active and non-missing samples N, sample index i, and mesh position k, the standard error is:
