PS296 Chapter Notes - Chapter 17: Factorial Experiment, Repeated Measures Design, Aaa Proteins
Document Summary
We use this when we have more than one independent variable at the same time. One way analysis of variance is an experimental design with only one independent variable. Two way factorial design: ex eyesnck study using two ivs age and recall condition. If you were to further classify participants as male and female, we would then have a three- way factorial design with age, condition, and gender as factors. An experimental design in which every level of every factor is paired with every level of every other factor (we include all combinations of the levels of the independent variables) Repeated measures is used when the same participant is included under more than one treatment combination. Factorial designs are better than one way designs beause they allow greater generalizability of the results and give us the ability to say something meaningful about the results for each of the. Factorial designs also allow us to look at the interaction of variables.
