Abstract
The Friedman test is also known as a two-way analysis on ranks. It is a nonparametric analysis method frequently used to analyze field and laboratory trial data in Human System Engineering group at DRDC Toronto. A BASIC program was previously developed to automate the data processing. However, due to the constraints of the programming language, the BASIC program has several intrinsic usability problems. This project was initiated with a goal to resolve these problems. Rewritten in C language, the new Friedman test program has improved its input/output capabilities, will perform post-hoc pair-wise treatment comparisons, and is able to run on multiple Operating Systems. This new program has successfully passed tests in several recent DRDC studies. It has been proved to be a useful analyzing tool and will benefit researchers in a wider range of future studies.
