How does a Three-Way ANOVA Work?
A pharmaceutical company, for instance, might execute a three-way ANOVA to ascertain a drug's effect on a medical condition. One of the factors would be the drug, another might be the gender of the subject, while the third might be the age of the subject. These three factors might each have a unique effect on the result. They might also interact with one another. The drug may positively affect male subjects, for instance, but might not work on males who are above a specific age. Three-way ANOVA permits the scientist to weigh the effects of each and if the factors interact.
