John wants to measure self-esteem among victims of domestic violence before and after they complete an 8-week program for abuse victims. Could he use a repeated-measures design and t-test for this study? Why? Give John directions for how to set up his study as a repeated measures design.Be specific about who, what, when, and how. Describe a kind of measure he could use for the DV that would result in scores that are on a continuous scale of measurement. Support your responses.
