Well that was fun!

[rzak]

howd everyone draw the regression line? just the normal way? did we have to give any points?

Well it wasn't a regression line. Btw did people section the points 4/3/4?

well then what was it? after you section it you join your points and move it 1/3rd...

if it was out of two you might get one, but consequentials are usually only when the thing you found wrong was a question on it's own, and then you used it in the next question, but in this case i dont think "find the ratio of volumes" or w.e. was a question

we had to find the height, and we were given ratio of radius's
 the next question asked to find the volume of it, so u needed the height for it.
i guess il get it if im lucky

look at question 3. then go and look at the assesment report, it was pretty much the same question as today

Lame paper. Hopefully the cut off is decreased, but messed up a lot of the bearings. Didn't think it was fair to be making comments about the relationship in the core module of age for any age group other than < 19 year olds. They all looked like the didn't have a very definitive pattern. Oh well.

Wait is a three median line also a regression line? lol

Anyway, i just did the moving ruler up a third towards the middle point thing.

no, big difference
regression=least squares= the sum of the squares of each residual is minimised
3 median = shitty guess that you can't rely on

Eh, well some people in the other thread are saying they calculated the regression line. The question asked for three median...

i guessed the height and used this value to find V (was running out of time). So would that give me consequential marks??

The question that asked you to mark the X on the three dots, was a "3 median line" question, not regression!

[Wisdumb]

I have to say I am thoroughly dissapointed with my effort today... I understood how to go about answering all the questions that I was allocated, yet as I look back now I can pinpoint so many silly mistakes that I made. I guess thats what exams do to you, hoping I can manage a 55/60 now.

yeh i didnt do regression, did 4,3,4 then joined upper and lower and moved 1/3, it was all  so messy though because 1/3 was so close

my bad mixed up regression and median did the right one though!

[colgate]

Is it alright for the median line to divide it into 3/5/3  then shift a third to middle?
or does it have to be 4/3/4

[grosry]

i love not reading the questions correctly... last question of matrices, i did year one not two, arhh!!
and some of those networks questionssss.... WTF!!

Hmmm I think they're meant to be pretty much equal.

theyre meant to be "as even as possible" with the two on the outer sides being equal
if you divided it 3/5/3 then i think theyd mark that wrong, though im never sure about these things now
