Dr. Phillips is а cоgnitive-develоpmentаl psychоlogist who studies how children leаrn mathematical principles. His current interest is in studying how children learn multiplication. He recruits 60 second-graders who have not yet learned how to multiply numbers to participate in his study. He is curious as to whether different teaching styles lead to better mastery of the subject. One Group (A) involves having students read a chapter on multiplication from their textbook. One Group (B) involves having students watch a video of cartoon characters explaining multiplication. One Group (C) involves having students being taught multiplication from a teacher. One Group (D) involves having students being taught multiplication by a fourth-grader. In all conditions, participants spend 30 minutes learning the fundamentals of multiplication and are then given the same 15-question multiplication test. The number of questions answered correctly was recorded. Students in Group A (the textbook group) solved fewer problems (Mean = 4) than students in Group B (mean = 10) and Group C (mean = 12.0), but not compared to Group D (Mean = 7). Name a way that Dr. Phillips could avoid selection threat when he is assigning participants to conditions and explain why the method avoids a selection threat to internal validity.
