AB  - The  statistical  procedures  we  have  described  thus  far  have  all  focused  on  the  comparison  of  a  measured  dependent  variable  across  categories  of  an  independent  variable.  These  procedures  are  generally  applied  to  experimental  and  quasi-experimental  designs  for  the  purpose  of  group  comparisons.  We  will  now  begin  to  examine  procedures  for  exploratory  analyses,  where  the  purpose  of  the  research  question  is  to  evaluate  the  relationship  between  two  measured  variables.  Where  statistical  tests  of  group  differences  address  the  question  "Is  group  A  different  from  group  B?"  or  "Does  this  treatment  cause  this  outcome?",  measures  of  correlation  ask,  "What  is  the  relationship  between  A  and  B?"  or  "Does  variable  A  increase  with  variable  B?"
