For each of the following hypotheses, identify the independent and dependent variables, and draw a fully labeled diagram showing how the hypothesis could be evaluated or tested using an experimental design. In your diagram, make sure you identify the attributes of the independent variable, along with a potential pretest and posttest to measure the dependent variable.

1. Studying at least 2 hours for a teest leads to a grade of at least a B on the test.
