# Java Applets

## for Statistical Methods for Psychology, 8th ed.

This web page points to sites that provide Java applets. A
Java applet
is a program that runs over the web. They allow you to
enter data or to
move sliders that alter characteristics of their canned
data. An applet
might show how a distribution changes as you change its
skew, or it
might show how the scatterplot of two variables as you
increase or
decrease the correlation between the variables. I am only
putting a few
links here, but you can find more by going to Google and
entering
"java applets statistics."

A very good set of applets for generating
simulations can be found at
David Lane's site at Rice. David has been writing
applets for some time, and is very good at it.

John Kane, at Oswego, has provided a great
set of statistical
calculators. These allow you to calculate, for
example, the
exact probability of a value of t
greater than or equal to the value you obtained with your
test.

There is an excellent site
that is really an online statistics course. It is aimed at
a somewhat
lower level than my course, but it has some first rate
stuff. It is free, although at a quick glance it might look as if you have to pay for it. I don't
know the authors, but I wish I did so that I could credit them. SurfStat is on a site run by the
University of Newcastle in Australia.
