Seeing Statistics

This page contains applets from McClelland's Seeing Statistics, which have been integrated with material in Fundamental Statistics for the Behavioral Sciences, (9th edition) by David C. Howell. You merely need to click on the appropriate link to open the applet, and then follow the directions on the page. BUT SEE NOTE BELOW!!

These applets will require that you have Java installed on your computer. You can very easily download that software for free by clicking on the following image. Just follow their instructions. (Be patient at first--it can take a while for the first image to load.)

Get Java(TM) Technology Now

However, beginning with Java version 7, update 51, Sun Microsystems made an important security change which defeats the purpose of many authors who write Java Apps like this. Sun now insists that all Java Apps have a security certificate. The lack of a certificate will normally prohibit the app you want to run from running. You can see how to get around this problem by going to, although they forgot to mention the Mac--but see below. What they suggest is that you add an exception to the Java program. If you are running a version of Windows before 8 or running Windows 8 the old fashion way--you have the old normal screen-- go to the start button in the lower left, click on "All Programs," select "Java" and then "Configure Java," and finally chose the "Security" button. (I assume that the same thing will work in Windows 10, but I do not have a copy of that operating system.) If you running Windows8 with all of the icons all over your desktop, swipe in from the right and select "Search." Then ask it to search for Java, and it will immediately come up with "Configure Java" as one of its choices. (On the Mac, click on the apple in the very upper left, select System Preferences, and then click on the Java icon.The screen you get will be essentially like the one below, but without some of the graphics.) In Windows you will get the following screen.

Notice that near the bottom is an "Exception List," with "" and "" You can add the same exceptions that I have by clicking on "Edit Site List ..." Put those exceptions in and click OK. You should now be all set to run. (I use both "http://" and "https://" because you can get to this page in different ways and some may not use the more secure https setting.) When you start Java by clicking on one of the Java Apps (e.g. "Why Divide by N - 1?"), it will ask if you still want to run the app. Click "Run." and you are all set. (If you have already got Java or your browser running, close it and then reopen it after adding the exception. If you don't do this your changes won't be in effect, so please restart your browser before continuing.)

If you are running Windows 8 as it came from the box, you have a screen filled with a million (well, lots) of icons. (It makes me feel as if I am playing some sort of children's game.) Search for an icon that says "Configure Java" and that will take you to the screen where you can click on Security and see the image shown above.
