A box plot represents the data divided into quartiles, each part of the plot shows 1/4 or 25% of the data.

Oh, I see but why is the answer Q1 if it's equal to 25%? So basically, Q1= 25% Q2= 25% and Q3= 25%

25% got less than Q1 so 75% got more than (exceeded) Q1

Box plots and stem and leafs haven't shown up in a while. Edexcel seem to love spamming histograms. June 15's histogram was extremely annoying

June 2013 R seems like a relatively tough paper - https://1a388b28f5ce9318f837a64962fc3ceab9c61da8.googledrive.com/host/0B1ZiqBksUHNYU2s1SVY1VDN2Q0U/June%202013%20(R)%20QP%20-%20S1%20Edexcel.pdf

Yeah, histograms are easy but it was just an unbelievable amount of work for 2 marks! Maybe there's an easier way I can't spot.

That conditional normal distribution probability bit was confusing. I haven't seen an S1 paper like that before.

I'm a bit stuck with interquartile range ... If I get a number (position) something point two five, am I suppose to take an average?

For instance, if it's 3.5 I'll take the average of both the third and fourth value but if I get 5.25 am I suppose to take an average of both the fifth and sixth value.

Here's two examples I got below, the first one is from the markscheme and the second one is from the CGP.
