I'm positive this question has come up on this list before, so my apologies - I do not have time right now to dig through the archives.
The 3rd edition of YMS makes a big deal out of stating "the sample makes up less than 10% of the overall population" as a check that observations within a sample can be considered independent of one another. However, I rarely see this mentioned as part of the check of assumptions/conditions on the AP scoring rubrics.
Can those of you who grade the AP exam address this? Is the above a statement they need to make for all inference procedures, or not?
