A team of educational researchers want to assess traditional classroom instruction compared to online options. Students who are enrolled in a course will be randomly assigned to one of two sections: Students in Section 1 will take the class in a traditional classroom. Students in Section 2 will take the course online with an interactive video cast of the instructor wherein students can ask the instructor questions during the session. The researchers will gather the course grade of each student (0% . . . 100%).
