Participants are given the Diagnostic Interview for Borderlines-Revised (DIB-R) before and after the 20 therapy sessions, to assess treatment efficacy. Based on the literature around BPD, you hypothesize that the DBT group will see the greatest improvement in DIB-R scores. 1) What measure of central tendency should you use to assess the dependent variable? And what is a potential confounding variable in this case? 2) What is your null hypothesis? What is your alternative hypothesis? 3) Is it directional or non-directional? and what statistical test would you use to assess your data?
