Identifying Independent and Dependent Variables 30 points Directions: For each example, identify the independent and dependent variables. Remember, the independent variable is the one that you change between the groups, while the dependent variable is the one you measure to see if it was affected. You can also think of it as independent as the possible cause and the dependent variable as the possible effect. 1. You give one rat sugar water and a second rat plain water. You then time how long it will take each rat to find its way out of a maze. 2. You put one group of people in a noisy room and another group in a quiet room. You give them both the same math test and compare the scores of the two groups. 3. You play sad music to one set of people and happy music to the second set of people. You then ask them to rate their mood as 1 being very sad, 10 being very happy, etc. 4. You compare the AP Psych scores of two classes. One class was an online class and the other class was a traditional face-to-face class.
