Statistics without Formulas! 
Download Statistics101 Updated 01/30/2017. Version 4.4 What's new  
The Wizards module of the latest version of Statistics101 requires Java version 6 or later. If your computer has an earlier version of Java and can't be upgraded to version 6, then the new Wizards module will be unavailable but the rest of the functionality will still be available. 
Statistics101 is giftware, with no time limit and no price. I hope you find it useful in your statistical teaching, learning, or research. If you have an example that you think others might be interested in, please consider describing it in a post on the  User Forum. If you have a question or a problem, you can either post it on the forum or email me directly

Linux Users, please read the following: 
To install Statistics101 under Linux: 
Download the installer from the website. It should work with Linux if you have Java properly installed. Don't let your Archive program try to extract files from it. Instead, you might have to run the installer in a terminal like this: 
  cd <directory containing the installer> 
  java -jar installStatistics101.jar 
Make sure you install the program into a directory in which you have full permissions.  
You might need to set the execute permission on the Statistics101.jar file. 
Once the program is installed, it must be run such that its working directory is the directory containing the Statistics101.jar file. So, probably the easiest thing to do is to create a command file containing commands similar to the following two, perhaps named "launchStats101": 
   cd <directory containing the Statistics101.jar file> 
   java -jar Statistics101.jar 
Then, whenever you want to launch the program, just invoke the command file.
Mac users, please read the following: If you get a dialog box reporting that "Statistics101.jar" can't be opened because it is from an unidentified developer, please see the following link on how to enable it to be opened:
