   have some questions
   
   first, i would like to know what are the similarities and differences for the above terms..
   
   also, a correlation coefficient ranges from -1 to 1 while correlation determination ranges from 0 to 1,
   
   why cant the correlation determination be negative?

   And the "above terms" are...?
   
   r may range from -1 to 1, but when you square it, then negative goes away. [itex](-.5)^2 = .25[/itex].
