Its also clear that there is no difference between the two treatment levels (psychotherapy and behavior modification). In such a design, the interaction between the variables is often the most important. Now she has three independent variables to look at: gender, difficulty, and time of day. The value must be a positive integer starting from 1, Multiply the integer with all of the integers lesser than it in a descending order. For example, the following code shows how to perform a two-way ANOVA for our hypothetical plant scenario in R: Heres how to interpret the output of the ANOVA: The following tutorials provide additional information on experimental design and analysis: A Complete Guide: The 22 Factorial Design The two levels for each of the drugs (or factors) is ''Yes, the patient received the drug.'' The outcome ranges from 1 to 10 where higher scores indicate more severe illness: in this case, more severe cocaine addiction. Although its tempting in factorial studies to add more factors, the number of groups always increases multiplicatively (is that a real word?).

As far as I can tell, the DV's data might not suit the requirements for normal distribution for an ANOVA since data is bounded 0 and 100, respectively. Factorial designs allow researchers to look at how multiple factors affect a dependent variable, both independently and together. A study with two factors that each have two levels, for example, is called a 2x2 factorial design. Subsequently, one may also ask, what is a 3x2x2 factorial design? 3-way Factorial Designs.
