Question

I administer a test of 100 questions. Since April 165 students have taken the test. I track all missed questions in order weed out bad questions. How do I calculate the percentage of questions missed based on all 165 students. For example on question 1, 22 students answered the question wrong. What percentage of students missed that question? Now I need to create a chart or graph on excel to indicate those percentages.

22 divided by 165 multiplied by 100.
