The researcher randomly selects a sample of 40 female breast cancer survivors (not involved in a regular exercise routine) who are then randomly assigned to one of two conditions (or groups): Following pre-tests on a quality of life index, the Experimental group (exp) took part in a structured strength training program for a period of six months while the Control group (contr) did not take part in the program.
