Statistics

Statistics is the language of experimental psychology.  It is a way for us to determine the validity of our findings and communicate that to others.

Understanding statistics is not only important for carrying out the internal assessment, but it is also important for reading psychological reports.

This section of the site is devoted to developing "statistical literacy."  The goal is to improve the analysis section of the internal assessment and develop critical thinking when interpreting the results of a study.
