I'm trying to create a control chart. I have 4 sample groups with different numbers of parts in each group. When trying to construct a control chart and picking the right constant I need "n" the problem is, is that n is different for each sub group. Can I not construct the control chart using this forumula if each subgroup has a different number of parts?
