A math teacher compared two methods for teaching division to his students. She randomly assigned 60 students into two equal 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. p = .03 in this research example means: Group of answer choices there is a 3% probability that Method A is more effective than Method B. the probability of correctness in drawing the conclusion. there is very small probability that Group 1 performed better than Group 2 in the post test. there is a 3% probability that the difference found between Method A and Method B (in favor of Method A) is due to chance such as errors in sampling or measurement
