An experimenter was interested in the effects of three types of therapy and gender on a measure of quality of life. She designed the experiment so that the male subjects were randomly assigned to the different therapies and the female subjects were also randomly assigned to the different therapies. The type of therapy was experimentally manipulated and after six months the outcome was measured. A two-factor design was used. How many independent variables are there in this design? Name each factor (using appropriate descriptors from the paragraph) How many total groups (cells) are there in this design? Name the dependent variable:
