Hey everyone,

I'm trying to do a control chart of a process, and I was having trouble with the subgroups.

Is the subgroup size the sample size of the product im inspecting? Thank you for your time.

Hi, I think subgroup size is the sample size they sound similar but I don't remember anyone referred the sample size as subgroup size, usually what you need to build control charts are:

samples - items values
samples sizes - defectives count

Which control chart do you have in mind so I can have a better idea of what you need.
