Dear Colleagues,

Two new confidence interval applets with user guides are available on
http://wise.cgu.edu

One demonstrates the 'overlap fallacy' (students and researchers alike
underestimate the amount of overlap for two confidence intervals when a
t-test gives p = .05.)

The second demonstrates how confidence intervals are computed and shows the
variability of confidence intervals as a function of sample size and
population shape, which can be manipulated.

Suggestions for improvements are welcome!

Cheers, Dale
