Question 8. Are you sure it's E? That doesn't quite make sense to me.

[anonymous 774]

I think question 4 in core is D as postcode is categorical. Don't worry I made the same mistake!

[anonymous 774]

I think question 6 in core is A

DAaaaaammit. I had this going through my mind but it's such a vast selection of categories so I decided to not include it in the sense that number of children could be considered categorical since it has a large amount of potential options. In my mind I thought it was just discrete data (postcode)

[Lucho23]

That Question 6 for Core was a tough one this year, however, drawing it on CAS produced A..not 100% though.
Question 9 for Core is B, -0.005, how'd you get C out of curiosity?
and Matrices Question 9 is C because B is actually the inverse of A

Question 8. Are you sure it's E? That doesn't quite make sense to me.

Which question 8?

[anonymous 774]

I got C for question 5 in matrices

[brenden]

That would've been for a single stemplot, for a back to back you need two categories.

AHhh fuck I'm retarded.
