Hi all: I just worked through the 2014 AP Statistics Free response questions, which are publicly available here.
Possible Free response solutions 2014 frq, Second Draft!
Those were my first attempt. Thanks to Corey Andreasen, Pat Humphrey and others who caught some errors!
Again, these are simply attempts at solutions, and they probably still have errors… so tear them apart! I invite corrections, critiques, questions, and commentary.
I look forward to the dialogue.
If they provide a starting point for further dialogue about the questions, then I have succeeded.
UPDATE: Thanks to Corey Andreasen for his on-point comments.
I agree with his critiques, but I also want to think more about 4a: Is there more to a complete solution than simply “means are pulled up by unusually high incomes, and medians aren’t?”
