This section is intended to be a quick reference for a selection of basic statistical tools for hypothesis testing. You can also calculate confidence intervals for most of these examples based on the descriptive measures. Before using this reference, review the definitions in the Statistical Terms Dictionary to help you determine which statistic is best for your project.
Consider consulting with a statistician. You can contact a statistician on the NEDARC staff. All statistical tests rely on mathematical assumptions which should be evaluated prior to using and interpreting the statistics.
