Document Summary
When researchers want to investigate the effects of more than one independent variable on a dependent variable. Crf design is a form of analysis of variance that permits a researcher to investigate the effects of two or more factors and to assess any possible interactions between these factors. The primary characteristic of this type of design is that each cell in the design is made up of a random sample of observations. Thus, in a two factor (ab) design, there are axb groups of observations and the researcher can assess the effects of the a factor, the b factor and the combination of a and b factors. In a three factor design, there are axbxc random samples of observations and the researcher can investigate the effects of a, B, and c by themselves, the two way interactions of ab, ac, and. Bc and the three way interaction of abc. In theory this can be extended to any # of factors.
