The June 2017 version below might be the final version of SPS. While I am able to do so, I will fix any "bugs" in the program that I become aware of, but no new functionality will be added to it. I want to thank Andy Delamater for his crucial help in getting the summarizing table of implied means for Rodger's two SPAs (split plot alternatives) incorporated into SPS in February 2015. This June 2017 version makes only trivial changes to the May 2017 version of SPS. If you are using any version of SPS that is older than that May one, you should certainly replace that with this current version.

If you want to replace an older version of SPS, then:

1) remove the program from your computer in the usual, control panel, manner;

2) delete the installation folder (called Application Files) and the ClickOnce Application Deployment Manifest file (called Simple Powerful Statistics.application) from wherever you put them (if you didn't do that immediately after previously installing SPS);

3) put their newer replacements somewhere on your computer (temporary shortcuts to these two installation components on your desktop are sufficient); and

4) click on the ClickOnce Application Deployment Manifest file (called Simple Powerful Statistics.application) to install this version of SPS.

Whether you are replacing an earlier version of SPS or intending to install SPS on your computer for the first time with the files below, you must successfully download at least the first and last of the four files below. This ersatz, new version of Google 'sites' makes this far harder to accomplish than the original version (slated to disappear forever by early 2019) did, so follow these steps:

1) Place your mouse cursor on "Last modified" and then left click on the square that appears to its right.

2) When the "SPS June 2017 version" page opens, select the 'Download all' option on the right hand side, and 7 files should (but sometimes fail to) automatically be zipped into a downloadable folder with garbage characters at the end of the name.

3) Select the option to save these files on your hard drive.

4) Navigate to your Downloads folder, find the SPS June 2017 version... folder with a .zip extension, and use the the 'extract all' option to put the 7 unzipped files on your hard drive.

5) Open the unzipped folder and install SPS by clicking on the Simple Powerful Statistics file, and answering any queries about whether you really want to install the program in the affirmative.

6) Finally, optionally transfer the "read me first" pdf document and the SPS data files folder to your 'Documents' folder prior to deleting the zipped SPS files folder. You can also optionally navigate to the location where SPS is saved on your computer, and click "send to" the desktop to create a shortcut to quickly open the program in the future.

Some comments regarding the STPid program downloadable below:

My STPid (Scheffé, Tukey, Planned implication decoder) computer program is provided for researchers who lack the good sense to use Rodger's method and the SPS program. It provides the huge statistical benefit of allowing researchers who use the Scheffé, Tukey HSD, or planned contrasts statistical procedures to make exactly J-1 statistical decisions, and then obtain the J implied population parameters that are logically entailed by those particular decisions. As with the implied 'true' parameters (usually, means) obtained with SPS and Rodger's "implication equation" (formula #26 in the Rodger's Method Wikiversity entry -- see link on the previous page on this website), these provide both the rank ordering of the population parameters and the magnitude of the differences between those parameters. By my reckoning, this is the most important benefit of using Rodger's method.

Multiple potential decision sets are automatically constructed for 8 or fewer population parameters evaluated with Scheffé's method, or when using the J x (J-1) / 2 pairwise comparisons that are available for Tukey's HSD method with J=7 or fewer parameters. J-1 contrasts must be manually entered by the users of the method of planned contrasts, and by the users of either the Scheffé or Tukey post hoc methods IF more than 8 (or 7) population parameters have been investigated.

See the instructions for downloading and unzipping the SPS files above to do that for these STPid files. The STPid installation process is identical to the one for SPS.
