    Today I sat the EDEXCEL Mathematics B 1st paper on statistics and probability. I found it really easy and am aiming for an A* but for the cumulative frequency diagram I starting my graph at 0 on the x-axis instead of 20 (as we were meant to). We were then asked to find the IQR from the diagram, which I found according to my diagram. Would I lose all the marks or would error carried forward apply?

Do you agree with the proposed ban on plastic straws and cotton buds?
