Question

7. You are trying determine the effectiveness of an online version of ECON 300 Luckily your university allows you to conduct an experiment where students who sign up for ECON 300 are randomly assigned to take the class online (treated) or to take the class the traditional way in the section they sign up for. All students are evaluated based on the same problem sets and exams. The following table shows the mean characteristics of the students that were assigned to take the course online, of those that took it the traditional way, the difference, and the standard error of the difference Treatment Control Difference Male 0.52 0.55 -0.03 (0.40) Year in school 3.31 2.70 0.61 (0.47) 3.11 0.22 (0.08) GPA 2.89 In-State 0.75 0.77 -0.02 (0.30) 0.05 -0.01 (0.10) Taking as elective 0.04 25 25 Comment on the success of the randomization. [Hint: check for balance] a. b. Suppose the mean final course score for the treated group is 78/100 while the mean final course score for the control group is also 78/100. Given your answer to part (a) do you think that this is evidence that the online course is no different from the traditional course in terms of test score outcomes? If you do not think so, which version course do you think might be better? Explain.

Total number of conditions = 3+2+1 = 6
