Null Hypothesis

In statistical hypothesis testing, it is the hypothesis that there is no effect or no difference, and any observed deviation is due to chance.

Control Chart

A graphical tool used in process control to display how a process varies over time, highlighting whether a process is in control or if there are signs of an out-of-control process.

Sample Means

Calculations of the average values derived from samples, representing estimates of the population mean.

Average Run Length

In statistical process control, the expected number of samples that will be taken before an action signal is generated.
