1. Go to the library and locate three journal articles in your area of interest which are experimental in nature (where groups are compared). Do the following:
a. Identify the independent and dependent variables.
b. For each dependent variable, specify how it is going to be measured and whether it is clearly defined.
c. For each independent variable, identify the number of levels of that variable. What other independent variables would you find of interest to study?
2. What makes a good hypothesis?
