The post hoc tests show that the scheme group was significantly different from the control group but not the post-scheme group, and the post-scheme group was significantly different from the control group. This indicates that the training scheme had a significant impact on the job performance of the employees in the scheme group compared to the control group, and that the post-scheme group maintained or improved their performance compared to the control group.
