One-way Anova of PTSD Data

One-way Anova of PTSD Data

Created by David Howell of the University of Vermont, this page was written as instructions for a SAS lab assignment, but the example can be used with other programs. The study compares three treatments for rape victims against each other and a control group to see which treatment is most effective at reducing Post Traumatic Stress Disorder symptoms. The resource provides : an introduction, procedures, conclusions and the data set. The author employs a careful step by step approach to explaining this type of variance testing. For this reason, this is a valuable resource for almost any more advanced statistics classroom.
