We have developed a new tool that simplifies Z-to-P and P-to-Z Transformations. It is available at


Unlike similar tools that handle one input score at a time, our tool computes Z-to-P and P-to-Z transformations over an entire set of input scores, saving users time and effort.

The tool facilitates the work of data miners, statisticians, or anyone that need to compute Z and P scores without having to consult Z statistical tables.

It is a great tool for students and teachers interested in Statistics.
