Questions Fréquemment PoséesPercentile Calculator

What is a percentile?
A percentile indicates the value below which a given percentage of observations fall. The 75th percentile (Q3) means 75% of values are at or below that number. A student scoring at the 90th percentile scored higher than 90% of all test takers.
What is the interquartile range (IQR)?
IQR = Q3 − Q1, the range of the middle 50% of data. It measures statistical spread without being affected by outliers. A data point is often considered an outlier if it falls more than 1.5×IQR below Q1 or above Q3 (the "fence" method used in box plots).
How is percentile calculated?
This calculator uses linear interpolation (Type 7), the default method in R, Excel's PERCENTILE function, and Python's numpy. For a dataset of n values sorted in order, the value at percentile p is found at position (p/100)×(n−1), with linear interpolation between adjacent values if needed.
