GoStats

Summary

• Home screen for launching GUI versions of stats utilities

Background

GoStats is a GUI application that combines the command-line statistics utilities described in Chapter 6 in the 1st edition of MacKenzie's book Human-Computer Interaction: An Empirical Research Perspective. With the release of GoStats, the command-line utilities are no-longer supported. Chapter 6 in the second edition (2024) features GoStats.

To run GoStats, your system must have the Java Runtime Environment (JRE). There is a good chance your system already has the JRE, so just follow the Quick Start instructions below. If you need the JRE, it is available from Oracle as a free download. Click here to visit Oracle's download site.

Quick Start

1. Click here to download GoStats.jar. Depending on your browser, you might need to right-click and select "Save link as...".
2. Put the JAR file in a directory somewhere in your workspace.
3. Double-click on the JAR file. GoStats launches and the home screen appears:

   

4. Click the radio button for the desired statistical test.
5. Click "Go".

Security Note

Since the link above leads to an executable .jar file, your browser might popup a security warning or block the download. Don't worry, GoStats is safe. You can allow the download. Its only purpose is to do statistical analyses on a data file you specify.

Installation

The first time GoStats executes, a directory called GoStatsExamples is created in the same directory as GoStats. About two dozen example data files are extracted and copied into the GoStatsExamples directory. These are the example data sets in the APIs for the statistics utilities. The files include all the data sets for the examples in Chapter 6 ("Hypothesis Testing") of MacKenzie's book.

Documentation

Consult the APIs for further details and tutorial examples. The APIs are accessed from the "View API in Browser" button that appears in the GUI for each utility:

You'll need an Internet connection to access the API.

If you have any questions, please contact me (mack "at" yorku.ca). I'm particularly interested to know of any errors, crashes, or confusing aspects of the UI. Comments or suggestions welcome.

Good luck.
