How to use the Midrank Percentile Rank Calculator
Use the reference sample and the target on the same scale. This is a rank convention, not interpolation of a percentile value or a distribution-based probability.
The calculation
Worked example
For 10,20,20,30, a target of 20 has midrank percentile 50%.
Assumptions and limits
Other rank definitions handle ties differently. The tool does not claim this sample represents a population or apply survey weights.
