The Correlation Coefficient

1. A shorter version of a scale to measure PTSD was compared to the well-known Clinician Administered
   PTSD Scale (CAPS) by administering both scales to a sample of subjects. The Correlation Coefficient was .31.
   Is the shorter version of the PTSD scale valid according to that criteria? What kind of validity is established in
   this way?
2. First, choose a single concept (social work concept). Then give 2 hypotheses in which that same concept is
   the independent variable in one hypothesis and the dependent variable in the other hypothesis. Label the
   independent and dependent variables in both hypotheses.
