Percentile calculator
Find an interpolated percentile in a set of numbers.
A clear answer. Here’s how.
Sorts values and uses inclusive linear interpolation at index (n−1)×p/100 (Hyndman–Fan type 7). Endpoints are the minimum and maximum. Other percentile conventions can give different results, especially for small samples.
