S1 Answers Thread

anyways looks like you guys did pretty well. Most of the people from my skool found it harder than expected!

yeah mine too - bit of a surprise after most people finding C1 comparatively easy... ah well!

For the histogram one I put because the class widths were not equal.

That is a load of rubbish I know. What was the real answer?

Continuous data

I needed just over half a page! And I wondered the same thing.

Oh, and 4 marks for a question where you had to do linear interpolation THREE times? WTF!? But 3 marks for a question on the d.r.v. page for about 3 lines?

I agree, it should have been at least 6!

But it didnt say that 45 was the next highest value below 63 !!!! It just said that 63 was the only value over 45, therefore you CANNOT just randomly go drawing it on your box plot!

Err, what?

If 63 is the only value over 45, surely that implies that 45 was the next highest value below 63...

I got 93.7L

I doubt it was 20 as someone said, cos it was a lorry on a 200 mile journey so its probably not 20.

LOL!

That took AGES. I don't think I have seen interpolation on an exam paper before.

Has it been on?

Yes. I also got 25/74 for one of them but I can't remember the rest. I think they have already been posted earlier in the thread.

Hey, a few people have asked this now - that first question, what to write for 6 marks? Do you reckon its ok for each one to put
eg first one - x and y are strongly negatively correlated. As x increases y decreases therefore the coefficiant must be negative. SInce the correlation is strong the coefficient will be over -0.7 .
I also put something about the data lying in the 1st and 3rd quartiles - but i think i totally just invented that on the spot !

Yeah they are 1 week and a day apart aren't they?

So far I have got: C1: 100/100
C2: 100/100

And I guess I have got: M1: 90/100
S1: 90/100

===> 380

480 for an A ===> 2 * 50/100 for C3 and C4 (2 D's)

That is my master plan.
