A math teacher compared two methods for teaching division to his students. She randomly assigned 60 students into two equal-sized groups. Group 1 was taught with Method A using an innovative and technology-based method, and Group 2 with Method B using traditional textbook oriented methods. A comparison of post-test scores indicated that the results were significantly different (p =.03) in favor of Method A. When the teacher examines the mean scores of the two groups, the difference was 5.5 points on a 100-point scale and the pooled standard deviation is SD=10. Based upon the analyses, the math teacher should conclude that: Group of answer choices Method A using an innovative and technology-based method can be more effective than and Method B using traditional textbook oriented methods in improving students' test score. There is no difference in the effect on the test score between using the two different methods for teaching division to his students. Method A using an innovative and technology-based method can be less effective than and Method B using traditional textbook oriented methods in improving students' test score. There is no practical significance
