AB The  statistical  procedures  developed  in  Chapters  2  to  4  are  appropriate  for  analyzing  the  results  of  experiments  in  which  the  variable  of  interest  is  measured  on  an  interval  scale,  such  as  blood  pressure,  urine  production,  or  length  of  hospital  stay.  Much  of  the  information  physicians,  nurses,  other  health  professionals,  and  medical  scientists  use  cannot  be  measured  on  interval  scales.  For  example,  an  individual  may  be  male  or  female,  dead  or  alive,  or  Caucasian,  African  American,  Hispanic,  or  Asian.  These  variables  are  measured  on  nominal  scales,  in  which  there  is  no  arithmetic  relationship  between  the  different  classifications.  We  now  develop  the  statistical  tools  necessary  to  describe  and  analyze  such  information.
