paired vs. independent (SAS) [General Statistics]
dear joshi !
in the case of two treatments A and B:
independent usually means: treatment A ist administered in n subjects and treatment B is adminstered in m DIFFERENT (i.e. independent) subjects
dependent or paired usually means: treatment A is administered in n subjects and after a period of time treatment B is administered in the same subjects.
NOTE: statistical analysis is different for these two scenarios
NOTE: a cross-over design is a special case of a "paired design"
hope this helps
