The problem of variable subgroup size for a p chart can be minimized by:
A) using an average subgroup size
B) changing the product
C) changing the production process
D) none of these

Question

Quizplus · Accepted Answer

Using an average subgroup size will help to reduce the impact of variable subgroup sizes on the p chart. This involves calculating the average number of units in each subgroup and using this value to determine the expected number of defects. This approach helps to provide a more accurate representation of the process performance and reduces the impact of variability. Changing the product or production process may not necessarily address the issue of variable subgroup sizes and may not be feasible in all situations.
