To properly score a test by percentage the educator should:

• A. Multiply by 100
• B. Divide the total correct answers by the total number of questions
• C. Add up the points
• D. Use a pass/fail threshold

Answer: (B)

To score by percentage, you measure how many answers are correct out of the total and then convert that fraction to a percent. Start by dividing the number of correct answers by the total number of questions to get the proportion. Then multiply that proportion by 100 to express it as a percentage. For example, 42 correct out of 50 questions is 42/50 = 0.84, and 0.84 × 100 = 84%. If the test uses different point values, you can compute the percentage by earned points divided by total possible points, then multiply by 100. The other methods aren’t the direct way to express the score as a percentage: simply multiplying by 100 without a numerator doesn’t give a meaningful percent, adding up points yields a raw score, and a pass/fail threshold is a decision rule, not the calculation itself.
