Textbook Question
Chapter 2.3, Problem 36E
A study of college students showed a temporary gain of up to 9 IQ points after listening to a Mozart piano sonata.

Suppose that you wanted to see whether there is a Mozart effect for students at your school. (Hint: See Examples 2.4 and 2.5.)
- a. Describe how you might design an experiment for this purpose.
- b. Does your experimental design include direct control of any extraneous variables? Explain.
- c. Does your experimental design use blocking? Explain why you did or did not include blocking in your design.
- d. What role does random assignment play in your design?
