Welcome to WISE!
Our goal is to provide students and teachers of statistics easy access to a wide range of
resources that are freely available on the Internet. We invite you to explore our website and
enjoy many wonderful statistics materials from around the world.
A special feature of WISE is the sequence of interactive tutorials on key statistical
concepts (sampling distributions, the central limit theorem, hypothesis testing, and statistical
power). The tutorials use dynamic applets that allow the user to explore relationships on their
own. Guided exercises are designed to help the learner to take full advantage of the applets to
gain a deeper understanding of the concepts and logic that underlie much of inferential
statistics.
We invite your feedback on WISE. If you find any errors, if you have suggestions for additions
or improvement, or if you find this site useful, we would love to hear from you. Drop us an email
at wise@cgu.edu.

New prep
calculator link
prep (the
probability of replication) is an alternative to
traditional null hypothesis significance tests (Killeen,
2005). The Association for Psychological Science
encourages authors to report prep rather than
p values
in
articles submitted to Psychological Science.
Peter Killeen has kindly
provided us with a
downloadable Excel workbook that provides
explanations and templates for computing prep
from raw data or from summary statistics.
Other Notes
"WISE Stuff" is a
compilation of statistical resources that might be
useful to both students and teachers.
NOTE: If WISE applets are not loading properly, download
and install the latest version of the free Java Runtime Environment.

support page.
