What is a percentile in statistics?
A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. For example, if a score is at the 86th percentile, where 86 is the percentile rank, it is equal to the value below which 86% of the observations may be found.
How do you find percentile statistics?
Calculating percentile
- Put your data in ascending order. When calculating the percentile of a set of data, such as test scores, arrange the values in ascending order, starting with the lowest value and ending with the highest.
- Divide the number of values below by the total number of values.
- Multiply the result.
Is the 95th percentile the top 5 %?

The formula for calculating percentile ranks is relatively simple and straightforward. Knowing only the distribution of scores, you can easily calculate the percentile rank for any of the scores in the distribution. The percentile rank formula is: R = P / 100 ( N + 1). R represents the rank order of the score. P represents the percentile rank.
