My students have just completed a test. I want to analyse their incorrect answers. I have created a spreadsheet in Excel. Some of the questions are all based on the same subject. If for example questions 1, 2 and 3 were all based on 'punctuation', I want to see the number of incorrect answers in the 'punctuation' category (e.g. questions 1, 2 and 3) combined but as a percentage of 26 (the total number of students who took the test). For some reason, the total percentage keeps going over 100% and I don't understand why.

Hi I am having some difficultly creating a graph that shows different total numbers and the percentage associated with that total number. For example, my totals are 217, 207 and 10 and I need each to have a different percentage 63.8%, 64.3% 55.6%. I tried adding a secondary axis but this generates a visual that is misleading because for example the line that overlays the bars will fall way above the smaller total which makes it look as if over 100% was capture when it is only 55.6%. I am not sure if any of this make sense but I thought it would be worth a try.
