Question: how to work out percentages from a questionnaire?
Answer: Divide the number of people who answered in the affirmative by the total number polled. In the example, 200 divided by 1,000 equals 0.2. Multiply the quotient you calculated in Step 4 by 100 to get a percentage figure. In the example, multiply 0.2 by 100 to get 20 percent.
