For the section A answers, question 7 (b), wouldn't the answer technically be 6,530,000 as the questions asks for the 'number of people', and the y-axis on the graph is labelled as 'Number of visitors (1000s)'?

Both are accepted

can anyone answer this question please?

d) the equation of a possible line of best fit is y= 0.9x + 5.25

(i) Give a practical interpretation of the value of 0.9 in the equation

(ii) The value 5.25 does not have a sensible practical ineterpretation. Explain why.

0.9 is the eg. cost for each unit.
5.25 is the starting cost
i think ?

omg, i'm stuck on that too!
what a hard topic!
all i know is that u do n/2 or n+1/2 if it's an odd.
or i might be talking about CF. :confused:

what are the grade boundaries like for this exam?

equation of a line:
y=mx+c
to work out m(gradient)=y2-y1/x2-x1
to work out c, see where the line will intercept y-axis i.e. when y=0.
simples :smile:

last year grade boundaries:
june 2010
1389 Statistics 1H Max-100 HIGHER
A*71 A58 B45 C32

is the spec changed?

Applying it is what i struggle with.
so do you guys reckon this is the easier of GCSE's?

and wow, 70% for an A* seems fair? i've already got 25% of the GCSE A*

Full course. But It may be possible there's a short course too, but I'm not doing that one :smile:

Yeah, most schools do it as a one year course (as most of it is quite straight forward) :smile:

I got an E my controlled assessment (because I had no idea about the subject and we were left to get on with it) is it still possible for me to get an overall A if I get an A* in the exam? What's the highest possible grade I could get now?
