Comparing the means of the control in the two tests, we can see that the mean in test two reduced. The same is true about the experimental group. This could be due to the time factor since test two was administered 3 months after the first one. Though it must be noticed that the obtained t value for the first test was 2.34 and for the second it was 2.93, which shows the experimental could still outperform the control in even a 0.01 level of significance. 5.
