i think they meant did you actually have the graph in front of you and draw the lines and get the answers (which obviously you did bc u sat the exam so...)

if i remember correctly i think it was a cumulative frequency graph with a curve already draw

you had to find the median and the interquartile range

So baffled at question 24a... How did you guys get that? I thought they weren't the same so I didn't cancel out, plus it was 2 marks
I think that you had times the whole fraction by -1 and then factorise the bottom and cancel out
