@leahleah Never or rarely ever. Sometimes they will release an MC exam. But that’s why they say you can’t discuss them ever. They often reuse/slightly change past MC questions for all AP tests
I bubbled the wrong AP number on my MC. Will they still be able to identify it as mine from the AP label? Is there anyone I can email about this?
@MrWiggles
You are wrong. A matched pair is part of blocking.
This will explain it to you

So the answer was grade and gpa.
@APmaster007 Indeed, I did admit that matched pairs is a specialized type of blocking if you happened to read an earlier post.
m/c is released every 5 years
@MrWiggles
i did read it. You said that you were not sure.
What did you guys put for the mc that was asking which one(s) is/are true:
I.
II.
III.
@APmaster007 What were the choices for I, II and III
@MrWiggles
No idea. I don’t even remember the question. All i know is I was kind of confused on it, and just picked II.
@APmaster007 I think i remember the question - i put II and III. it was asking which would be effected by nonresponse
@MrWiggles
Ohh yeah, it did ask that. I was not certain if it was II and III or just II. So I just put II.
I think the answer involved if a mail was sent to employees.
I. was more women got the mail then men, and they chose a random sample or something
i don’t remember II or III
We need someone to confirm on the right answer.
@APmaster007 I think I put just II but I was unsure about that one
I think III should also be included, because it’s essentially the same thing as number 2. #3 was almost the same as #2 but it added on the fact that you’re taking a random sample of those who responded, would still be effected because the population you are taking the sample from is effected from nonresponse bias. So say you have 1000 people, and for both surveys 300 people responded. for number 2, it’s obvious that these 300 people are just the more avid people and wanted to respond/some sort of bias that would have occurred. In scenario 3, those 300 people, whose results are ALREADY skewed, have a random sample taken from them. so you’re taking a random sample of a population that’s from a bad population, which is why i chose II and II. It seemed logical to me to choose that
@MrWiggles @APmaster007 I put II and III. I feel like three definitely counts, because whenever you do a survey and not everyone replies, there’s a bias, either under-coverage bias or voluntarily response bias
Is the frq section released soon then?
Yeah I struggled on 2 and 6 the most
@MrWiggles
i don’t know. You make a good point. I would have to actually see the question again to actually decide.
I feel like that question is there to trick people. I don’t know. We need more people to confirm on it. One person says you are right, one person says I’m right so far…
I also picked II and III. And my reasoning is the same as MrWiggles
okay, so for FRQ #6, i said:
a) no, Method 2 would not be representative of the population of all tortillas made that day
b) Method 1
c) Method 2
d) i don’t remember what i said but probably got it wrong
e) Method 2, but i was unsure…
f) Method 1
did anyone else get the same answers for all of mine except “d”? i don’t remember my explanations why for some of these, but yeah
