AB The  procedures  for  testing  hypotheses  discussed  in  Chapters  3,  4,  and  5  apply  to  experiments  in  which  the  control  and  treatment  groups  contain  different  subjects  (individuals).  It  is  often  possible  to  design  experiments  in  which  each  experimental  subject  can  be  observed  before  and  after  one  or  more  treatments.  Such  experiments  are  generally  more  sensitive  because  they  make  it  possible  to  measure  how  the  treatment  affects  each  individual.  When  the  control  and  treatment  groups  consist  of  different  individuals,  the  changes  due  to  the  treatment  may  be  masked  by  variability  between  experimental  subjects.  This  chapter  shows  how  to  analyze  experiments  in  which  each  subject  is  repeatedly  observed  under  different  experimental  conditions.
