I think it might be Xbar-R Charts since they deal with averages and ranges, but I could be mixing it up with something else.

I feel like Time Series Charts are more about trends over time, so they probably don't fit this question.

I remember practicing with P Charts and NP Charts, but I can't recall which one has varying control limits based on sample size.

I'm not entirely confident, but I think the answer is C. The control limits for Xbar-R charts are calculated based on the sample size, unlike the other chart types mentioned.

Okay, I remember learning about this in class. The control limits for P charts and NP charts don't depend on the sample size, but for Xbar-R charts they do. I'll select option C.

Ugh, I knew I should have spent more time studying control charts. Well, I'm going with C and hoping for the best. Maybe I'll get lucky and the 'Xbar-R' part will jog my memory.

Ha! I bet the test writers were trying to trick us with those other chart types. Xbar-R charts are the only ones where the control limits change with sample size. Easy peasy!
