| (a) Write your best question using the stem. | Look for: A question with one IV and one measurable DV, a precise operational definition, and a feasibility reason. | 1 | ||
| (b) What is your operational definition for the DV? | Look for: A question with one IV and one measurable DV, a precise operational definition, and a feasibility reason. | 1 | ||
