The table 2 below presents the test of significance between the pretests of both the experimental and controlled group.
The results show that there is no significant difference between the means of the pretest of both experimental and controlled group as indicated by the computed t-value of 1.29 which is greater than the critical t-value for two-tailed t-test of 0.26 at 0.05 level of significance. For that reason, the decision is to accept the null hypothesis (Ho) that the means have shown their differences insignificantly.
This emphasized that the performances of the students before the implementation of the study do not differ with regards to their academic achievements.
