What is the Percentile Calculator?

Estimate a selected percentile from a numeric dataset. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.

Formula or method

Percentiles are calculated on sorted data using linear interpolation at position (n−1)p.

How to use this tool

Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. The 50th percentile corresponds to the median under this method.

Interpretation and limitations

Percentile definitions vary across software, so record the chosen convention when reproducibility matters. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
