What is Percentile Rank?
Percentile rank indicates the percentage of scores in a distribution that fall below a particular value. It tells you where a specific score stands relative to others.
For example, if your test score is at the 80th percentile, you scored higher than 80% of the test-takers.
Percentile Rank Formula
Percentile Rank = (L / N) × 100- L = Number of values below the score
- N = Total number of values in the data set
Example
Test Scores: 45, 55, 60, 70, 80, 85, 90, 95
Find the percentile rank of a score of 75.
- Values below 75: 45, 55, 60, 70 → L = 4
- Total values: N = 8
- Percentile Rank = (4/8) × 100 = 50%
- Interpretation: A score of 75 is at the 50th percentile (median).
Percentile vs Percentage
Percentage is a score out of 100 (e.g., 85% correct). Percentile is a ranking against others (e.g., 85th percentile = better than 85% of people).
Frequently Asked Questions
Is a higher percentile always better?
Usually yes, for things like test scores. But for metrics like wait time, lower percentiles are better.
What percentile is the median?
The median is the 50th percentile—half the values are below it, half are above.
