Definitions:

Normal Distribution

It is characterized by a symmetric shape around the mean, where data samples are more densely populated close to the mean and less so the farther they are from it.

Inside Diameter

The measure of the distance across the innermost part of a hollow object or space.

Lower Control Limit

A threshold value in statistical process control below which a process is considered to be out of control on the lower side.

Rational Subgroups

Groupings within a data set that are formed based on logical or natural relationships, often used in quality control to evaluate variation within and between these groups.
