Definitions:

Sample Means

The average values obtained from multiple subsets of a population.

Pooled Standard Deviation

A method used to estimate the standard deviation of several different populations when the mean of each population may differ but the true standard deviation of each population is assumed to be the same.

Lower Control Limit

The lowest value on a control chart, indicating the threshold below which a process output is considered out of control.

Sample Means

Calculated averages from different samples within a population, used in statistical analysis for comparisons.
