Two students, A and B, appeared in a test and scored 25 and 75 marks respectively. What is the percentile rank of A?

Correct answer: 25. Percentile rank = (number of scores below + half of the scores equal to the score) ÷ total × 100 = (0 + 0.5) ÷ 2 × 100 = 25.

• 50: 50 would be the percentile rank of a middle score among the group.
• 45: 45 does not follow from the percentile formula.
• None of these: “None of these” is incorrect because 25 is correct.
