Definitions:

Standard Errors

Measures of the variability or spread of sampling distribution estimates, indicating how much sample means differ from the true population mean.

Sample Mean

The average of a set of numerical values.

Control Limits

Statistical boundaries set in control charts that are used in process control to detect times when a process is out of control or behaving anomalously.

Standard Errors

The standard deviation of the sampling distribution of a statistic, typically the mean.
