NOTES FOR THIS VERSION: A new plot has been added. This plot lets the user create an X versus Y plot for multiple groups. For example, one can plot achievement scores of students against the year of testing for multiple schools. It is slightly related to the bubble plot procedure added several revisions earlier.

NOTES FOR THE PREVIOUS VERSION: The distribution comparison procedure has been modified. A slight modification of the procedures for saving files has been made. If you have not updated for awhile, a plot procedure was added that lets the user create a scatter plot of one X variable against multiple Y variables. This may be useful for comparing several repeated measures on the same group. For example, one might plot pre-test and post-test scores against student ability scores. Or one might plot a series of stock prices (the Y variables) obtained at different time periods against those time periods (the X variable.

OpenStat is a general purpose statistics package that you can download and install for free. It was originally written as an aid in the teaching of statistics to the students enrolled in a social science program. It has been expanded to provide procedures useful in a wide variety of disciplines. It is not a "finished" product but revised several times a year. The version is denoted by the month, day and year. For example 1.27.08 would indicate a revision released in January 27, 2008. The program is NOT to be used for commercial purposes and there is no warranty implied. Most users check results by hand or compare to commercial packages to which they have access to insure the results are correct.

You are invited to join the OpenStat discussion group sponsored by Yahoo Groups. You can find it at: http://tech.groups.yahoo.com/group/OpenStat/ That site provides users an opportunity to exchange ideas and problems they may encounter in using OpenStat. From time to time there are tutorials that may help you in your research or instructional activities.

There are two versions you may download:

1. The first is in a compressed file created by a free software program "INNO". The file is named OpenStatSetup.exe. After downloading the file, double click the file name (or use the Windows Run window) to begin the installation on your Windows system. I suggest that you do NOT select the option to create a desktop icon. By default the program and help files will be installed in a directory labeled C:\OpenStat. After you have installed the program you may open the folder where the program was installed and then click on the OpenStat.exe file to begin the program. Linux users may find that the free Wine software will allow them to run the program in their version of that operating system.
2. The second version is one is a ".zip" file that contains the more typical Windows type of installation using the InstallShield software. By default it will place the program and help files under the C:\Program Files directory. Use your "zip" program to unzip the file into a temporary folder. You will find a file labeled "Install.exe". Double click that file name and the installation will begin. After installing you can double click the "OpenStat.exe" file label to start the program.

If you are a Linux user, you may want to use the LinOStats form of OpenStat. It was written using the free Kylix package by Borland.
