In a class of 300 students, John’s rank was 40. Find his percentile rank
(300-40)/300 = ?
288
if paul ranks 30th in his class of 120,what would be his percentile rank?
To find John's percentile rank, you need to compare his rank (40) with the total number of students in the class (300).
Percentile rank is a measure that indicates the percentage of people who rank below a certain point. It is calculated by dividing the number of people who rank below a given point by the total number of people and multiplying the result by 100.
Since John's rank is 40 and the total number of students is 300, you can find his percentile rank by following these steps:
1. Subtract 1 from John's rank: 40 - 1 = 39. This adjustment is necessary because percentile rank is usually calculated with ranks starting at 0.
2. Divide the adjusted rank by the total number of students: 39 / 300 ≈ 0.13.
3. Multiply the result by 100 to convert it into percentage form: 0.13 * 100 ≈ 13%.
Therefore, John's percentile rank is approximately 13%. This means that he is ahead of 13% of his classmates in terms of rank.
