The summarized data can be viewed in the report window, printed, or saved to an output file you specify by clicking the appropriate tab in the report window. After viewing the report window, click the graph tab to view bar graphs of summarized data.

A spreadsheet output file is also available so data summaries can be manipulated for further for further analysis For example spreadsheet statistics can be applied to these columns to obtain variance, standard errors, etc of the sample.

We suggest creating a shortcut on the desktop to run the program. Once the data has been entered into an Excel spreadsheet, double click on the shortcut icon to run the program.

As with all freeware, this program and the data presented here come with absolutely no guarantee. We recommend checking the results of the first and last plots in a data file by hand to make sure everything worked correctly. We'll be happy to entertain questions and comments. Contact us at:
