I thought nP and P Charts were for attribute data, so I don't think D) is the right answer, but I can't remember why exactly.

I'm a bit confused about whether to choose C) Xbar-S Charts instead. I know they also deal with variability, but I'm not clear on outliers.

I practiced a question like this, and I feel like B) Xbar-R Charts might be the right choice since they deal with subgroups.

I think I remember that Xbar-R Charts are good for continuous data, but I'm not sure if they handle outliers well.
