=+14. The control limits on x charts become closer together as the subgroup size n is increased
Question:
=+14. The control limits on x charts become closer together as the subgroup size n is increased (i.e., the A2 factor decreases as n increases). For a process that is in statistical control, does this imply that a control chart point is more likely to fall outside the control limits of an x chart based on a larger subgroup size rather than a smaller subgroup size?
