I don't know what they teach in high school AP CS, but most such courses only lick the surface and are incomparable to proper college courses. Taking AP credit is only advisable for elective courses that does not require much rigor.
Especially for something as subtle and delicate as statistics, it would be better for the kids to learn the subject properly with the necessary rigor in college. The damage due to half-assed stat learning is all too prevalent in much of academia, especially softer sciences and social studies.
Things are not as simple as they seems at first. - Edward Thorp
