Install Stats Homework

 

Make Sure You Have Java

In order to run Stats Homework, you must have a current version of the Java Runtime Environment (JRE) on your computer. Visit http://java.com to test, install, or update your JRE.  On Mac systems, you will need to change the permissions on your system to allow the installation of a programs that don’t come from the App Store.  Research web sites like this one to see how to do this.

Working with Java’s Jar Files

Stats Homework is packaged in a executable Java archive file (.jar) that you can install wherever you would like on your desktop or in the file system on your hard drive. On most systems, all you have to do to run this software is to download it from its web page and double-click the archive file on your computer.

When you download this software package, you will have a file called, ‘Stats_Homework.zip’ located in your Downloads folder, or wherever you have your downloaded files stored.  Unzip this file to produce the Stats_Homework.jar file. You should be able to run this program by simply double-clicking this file.

However, you probably do not want this file to be stored long-term in your downloads folder since you probably clean out this folder from time to time. You should move the Stats_Homework file to another location so that it can reside peacefully on your system and so that you can access it whenever you want.

Perhaps the simplest solution is to copy the Stats_Homework.jar file to your your desktop and double-click it whenever you would like to run the program. Many users will store the program elsewhere on your hard drive and then have a shortcut/alias link to the program on your desktop or Dock.

On a Windows system, you might create a new directory named ‘statistics’ under the directory ‘Program Files.’ Move the Stats_Homework.jar file into that directory. Then, you can create a shortcut link to this file by right-clicking on this file and choosing Send to then Desktop (create shortcut).

On a Mac system, you might move the Stats_Homework.jar file into your Applications folder, and then create a shortcut link to it by right-clicking this file and choosing Make Alias. Move this shortcut file to your desktop, and then just double-click it any time that you would like to run Stats Homework. Or, drag the Stats_Homework.jar file to your Dock (note: you will have to place it on the right, next to your Trash can).

Troubleshooting

If you have difficulty getting Java programs to tun from the .jar file, here are two things to try.  First, open a command-prompt or terminal window on your system.  Enter the following command:

java -version

Java should return a simple message about which version of Java JRE is currently installed on your system.  For example, mine tells me:

java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

If you do not get a message like this one, you probably don’t have Java installed properly.  Go to Java.com and install Java on your system.

Next, sometimes Java will be installed on your system, but will not automatically open and run .jar files like Stats_Homework.jar.  Sometimes, your system will treat a .jar file as an archive file and open it as a folder.  You want to be able to double-click on the .jar file and have it execute the program.

If this is your situation, run this tiny utility program: run the jarfix utility.  This little program will establish the proper associations on your system so that .jar files will run with a double-click.
