Control Chart Construction

1. Take measurements of the characteristic being studied.

3. Calculate subgroup average X-Bar

Sum of values divided by number of samples (n)

187 / 5 = 37.4

2. Calculate sum of measurements

Add up sample values

33+38+31+43+42

4. Calculate Range

Highest value - Lowest value

43-31=12

Don’t Forget The ‘Details’ !!!

Lowest value

Highest value
