Section 4- JAVA Demonstrations
The emergence of JAVA as a platform-independent Web programming language
has encouraged individuals to develop interactive demonstration software
which can be accessed over the Web. NOTE: Although you can link to these
sites with almost any Web browser, you must use a JAVA-capable browser
to see and execute the applets.
Some of our favorite individual JAVA applets (selected from the sites
The sites below contain collections of JAVA applets or links to applets
at various locations which are relevant to statistics instruction.
Statistics Packages available as JAVA applications over the Web:
Correlations - a neat "game" to show the relationship between correlations
and scatterplots - ten minutes should get the ideas across to almost any

of a Hypothesis Test - nice graphical look at power for a test of a
mean (Todd Ogden - S. Carolina).
Problem - as implemented at UIUC lets you see how everyone else has
done, while the
Make a Deal version done by Webster West is a bit quicker to play and
includes an explanation.
Reese's Pieces - a simulated alternative to M&M's
