Document Summary

Simple experimental design is when one independent variable is manipulation with two levels and one dependent variable is measured. By the end of this lecture, you should be able to: Define a factorial design and discuss reasons why a researcher would use this design. Describe what information is provided by main effects and interaction effects in a factorial design. Interpret graphs depicting the results from a 2 x 2 experimental design. Discuss the role of simple main effects in interpreting interactions. Compare the assignment of participants in an independent group design, a repeated measure design, and mixed factorial design. An independent variable can have more than two levels or groups or conditions. Better understand the relationship between the independent and dependent variable. Example: consider a study where two groups of people are compared on their performance on a motor task. One group is promised for high performance, whereas the control group is not promised a reward.
