How to use this tool?
Follow these steps to calculate a percentile for your dataset:
- Enter your dataset in the "Dataset" field as comma-separated numbers (e.g.,
10, 20, 30, 40, 50). Decimals are allowed. - Set the percentile (0–100) in the "Percentile" field. The default is 50 (median).
- Click "Calculate" to get the result.
The result shows the interpolated percentile value. The explanation below details the sorted data, rank calculation, and linear interpolation used.
Tip: Ensure all values are numeric. Invalid entries will show an error.

Frequently Asked Questions
A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls.
The calculator sorts the data, computes the rank = (percentile/100)*(n-1)+1, and then linearly interpolates between the floor and ceil values of that rank.
Duplicate values are handled correctly; the interpolation method still works as expected.
