From: | To: |
Percentile rank indicates the percentage of scores in a distribution that a specific score is greater than or equal to. It's commonly used in standardized testing, statistics, and data analysis.
The calculator uses the percentile rank formula:
Where:
Explanation: The formula calculates what percentage of the total values are below the specific value you're examining.
Details: Percentile ranks help compare individual performance to a larger group, showing relative standing rather than absolute scores. They're widely used in education, psychology, and business analytics.
Tips: Enter the count of values below your score (L) and the total number of values (N). Both must be positive integers with L ≤ N.
Q1: What's the difference between percentile and percentile rank?
A: Percentile indicates the value below which a percentage of data falls, while percentile rank shows the percentage of data below a specific value.
Q2: What does a percentile rank of 75 mean?
A: It means the score is equal to or better than 75% of the scores in the distribution.
Q3: How is this different from percentage?
A: Percentage measures absolute performance (e.g., 80/100), while percentile rank measures relative performance compared to others.
Q4: Can percentile rank be 100?
A: Yes, if a score is higher than all other scores in the distribution, its percentile rank is 100.
Q5: What's considered a good percentile rank?
A: This depends on context. In testing, higher is generally better, but interpretation varies by field and application.
