the mean score of this group was 68.0 In addition, it can be seen that the total scores of pre-test in control group was 2133. Furthermore, the maximum score
was 76.7, the minimum score was 46.7 and the mean score of the students’ result
in this group was 66.7. The result of pre-test in control group was slightly different from the experimental group see Appendix 10 11. As a result, the
writer concluded that two groups had equal level vocabulary mastery before getting the treatment, therefore, the experiment could be continued.
