IT WAS SO SEXIST! I was silently fuming when I read that question.
Maybe it was a testosterone level test, who knows
2. Hey,would it matter if
Q1
-you used the values of 3.s.f to work out the pmcc
Q6
-that I left the standard deviation as 1.49

Thanks

If I have Q6b as 2.74% rather than 0.0274 will I get the marks?
you're right because they asked for PERCENTAGE
4. Aah I didn't even read a question properly! and I missed one out! Working out q3 then IQR :/ hoping for around 65

it said give as %, think arsey's sol'ns don't have % but should.

kinda struggling to prove to the sexist person who wrote this paper that girls ARE better at maths after calculating my total marks.
> The paper is sexist
> Girls are better

The irony is beautiful.

Hahaha, GO TEAM!
9. Can't remember all my answers. Feel like I may have lost lots of little marks.

Mark could be anywhere from 60-70. Hopefully top end...
10. Hey for question 4 isn't the data negatively skewed, I mean q2-q1 is more than q3-q2 ...I put that it's not symmetric and it's skewed and then I did the formula above to show its negatively skewed...is that right

for the venn diagram question i put three circles, the first being full time, second being bus and third being contract. Therefore the area that full time and contract doesnt intersect bus, its part-time that gets the bus, and the bit outside the circles is part-time which doesnt get the bus.
Surely this is more right than having a centre circle of 0?
I too did this, thinking it was more right, but I also gave the 4 circle solution but I put a pencil line through it. Can I still gain full credit even if I have given 2 solutions and put a faint line through one of them?
12. How many marks lost for NOT doing to 3SF in part a??

I did that too! i honestly don't know how i missed that :/

Basically I used the wrong value from the formula sheet.

But I used the actual formula : X-mean/sd = the figure from formula sheet
In that case I reckon you'll pick up some method marks at some point
15. well i ****ed that up - in past papers was getting like 73/75, ill probably get like 55-60 on this ****...the regression equation was ****...would i lose all 7 marks for that question all because i got the equation wrong???
16. Also in 6c, I drew the diagram like in the mark scheme but found 0.99, crossed it out and found 0.98 in the table - then obviously went from the right standard deviation to the wrong one - how many marks lost?

Me too!

I gave them to 2dp. ugh. life.
19. Does anyone have any idea where international students can get model solutions for our paper?

I was fuming because I couldn't do the Venn diagram!
Naah smashed that question, took me about 10 minutes of staring at the data for the answer to appear but eventually it did!
