Extracted text: Question 8 A study was conducted to determine the effectiveness of YouTube Video Clips in teaching statistics to graduate students. Equal number of graduate students were assigned to three different treatments: Lecture with video clips, Lecture without video clips and Small group teaching. The results are shown in the tables below: Table 1 Treatment Lecture with Video Clips Lecture without Video Clips Scores in Statistics Std. Deviation 3.05 Mean Std.
