X AND R CHART EXAMPLEIN-CLASS EXERCISE

The following collection of data represents samples of the amount of force applied in a gluing process:

Determine if the process is in control

by calculating the appropriate upper and lower

control limits of the X-bar and R charts.

Example of x-bar and R charts: Step 1. Calculate sample means, sample ranges, mean of means, and mean of ranges.
Example of x-bar and R charts: Step 2. Determine Control Limit Formulas and Necessary Tabled Values
