 * Hypothesis:** A psychology teacher believes that listening to music while studying will increase students' retention. Design an experiment to prove or disprove her theory.


 * 1. Independent variable**: yes music or no music


 * 2. Dependent variable**: test results

- Students are all 17 years old - their hair does not get in the way of their eyes - they all use the same pen given by the experimenter - they all memorize and take test at the same time (afternoon is preferred)
 * 3. Control variables**:

- 40 students are experimented (choose 10 from four different schools because surveying students from only one school might be too biased). - 40 students all sit in one room and start memorizing SAT words - After 30 minutes, the teacher tests students - The next day, at the same time, students gather again in the same room. This time, music will be played while memorizing a new set of SAT words - Teacher gives out the test - The experimenter can then compare test results. If the second day's result is better than that of the first day, the hypothesis is proven.
 * 4. Experiment:**
