Welcome to the Companion Site!

This site is intended to enhance your use of Statistics for Human Service Evaluation, First Edition, by Reginald O. York. Please note that all the materials on this site are especially geared toward maximizing your understanding of the material.

This practical book shows how both Excel® and SPSS® can be used for analyzing data for human service evaluation. Assuming no prior instruction for statistics, the text utilizes a “learn by doing” approach: readers see the use of statistics demonstrated and then are encouraged to apply their own data to statistical analysis with step-by-step guidance. Decision trees, practice exercises, and quizzes ensure readers will be well prepared to practice data analysis in a wide variety of human services situations.


We gratefully acknowledge Reginald O. York for writing an excellent text and creating the materials on this site.
