Quizplus · Accepted Answer

The effect of a cause is determined by computing the difference between the initial and final group differences. This allows for the comparison of the changes that occurred due to the cause in the experimental group versus the control group. A and B only consider one point in time, while D is not a valid method of analysis. Therefore, C is the best choice for determining the effect of a cause in an experiment.
