A simple, pre-post design is often used to compare group differences over two time points. However, the statistical analysis does pose some questions. This talk outlines some options available to analyse two-group, pre-post data, including repeated measures, analysis of (co)variance, change scores and mixed models.
The speaker is Nancy Briggs, Senior Statistical Consultant, Stats Central. Nancy has extensive experience in many statistical techniques over a range of discipline areas.
