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: Excel's summary results at the 0.05 level produce the following output:
Using this output, what conclusions can you draw?
A) Since the calculated F-value is smaller than the F-critical value, there is a significant difference in the methods of teaching.
B) Since the calculated F-value is smaller than the F-critical value, there is no significant difference in the methods of teaching.
C) Since the P-value is 0.001, there is a 10% chance of these results happening when there is no significant difference in the methods of teaching.
D) Since the calculated F-value is larger than the F-critical value, and the P-value is so small, there is strong evidence to suggest that all teaching methods do not give equal test results.
E) Since the calculated F-value is larger than the F-critical value, and the P-value is so small, there is strong evidence to suggest that all teaching methods give equal test results.
