The mean difference is significant at the 0.05 level. a. Group 1 to Group 2: Different / Not Different The Significant value =0.000, so conclude that these groups are significantly different. b. Group 1 to Group 3: Different / Not Different The Significant value =0.000, so conclude that these groups are significantly different.
- 4. c. Group 1 to Group 4: Different / Not Different The Significant value =0.000, so conclude that these groups are significantly different. d. Group 2 to Group 3: Different / Not Different The Significant value =0.001, This value is less than 0.05 so conclude that these groups are significantly different at 5% level. e. Group 2 to Group 4: Different / Not Different The Significant value =0.000, so conclude that these groups are significantly different. f. Group 3 to Group 4: Different / Not Different The Significant value =0.722, A high p-value indicates to accepting the null hypothesis. so conclude that these groups are not significantly different.
