In an effort to determine the most effective way to teach safety principles to a group of employees, four different methods were tried. Some employees were given programmed instruction booklets and worked through the course at their own pace. Other employees attended lectures. A third group watched a television presentation, and a fourth group was divided into small discussion groups. A high of 10 was possible. Samples of five tests were selected from each group. The test grade results were: Using Excel to assist in determining if all methods generate the same results, what test would be used?
A) ANOVA: Single Factor
B) ANOVA: Two-Factor with Replication
C) ANOVA: Two-Factor without Replication
D) F-Test Two Sample for Variances
E) t-Test: Paired Two Sample for Means
