QUESTION 6 Imagine that BCC would like to test the effectiveness of its tutoring programs. BCC hires several tutors who are experts in their subjects, but also hires actors who pretend to be "tutors" though they know nothing about those subjects. At the end of the semester, all of the 2,000 students being tutored say they understand their classes better, even the 1,000 students whose tutors were really actors. Before the study began, the BCC researchers were careful to make sure that the tutoring study only included full-time students who had not already failed the course, and whose GPA was at least 2.0. Also, each student had to receive exactly one hour of tutoring per week. This shows that the researchers wanted to be clear about: A. Random Assignment B. Random Selection OC. Operational Definitions D. Informed Consent QUESTION 6 Imagine that BCC would like to test the effectiveness of its tutoring programs.
