An analysis of variance, or ANOVA, is the main statistical tool used in human-computer interaction experiments. It is used to answer research questions such as "Does the time to complete a task depend on which of several interaction methods is used?" In studying the analysis of variance, I found it useful to write a program to perform the test. It was quite a grind, but I learned from the exercise. The program is in Java. While working on it, I wrote the API to explain the details. Both the program and API are used in my teachings, and they are usually placed on a web site for students to download. It seemed worthwhile to add them to the Research Notes on my home page, so here they are:
· API (read here for all the details)
· Download site (click on Anova2.zip)
