The mark scheme I have attached is for a question where I had to draw a cumulative frequency graph and find the IQR from the graph after drawing it. If I got 4 points correct (as stated on the mark scheme) but got the 5th one wrong, would I lose just 1 mark there. Also, if I got my IQR as 2350, which is just outside the required range, am I right in saying that I would not lose any marks on part d) because my IQR is right according to my graph.

How many marks would I lose for this question? watch
