Based on the description of data in both control class and experiment class above, it can be concluded that the result of pre-test in control class; the
lowest score is 24 and the highest score is 60. Meanwhile, the result of post- test in control class; the lowest score is 28, and the highest score is 72. On the
other hand, the result of pre-test in experiment class; the lowest score is 28 and the highest score is 56. Meanwhile, the result of post-test in experiment
class; the lowest score is 40 and the highest score is 72. Therefore it can be summarized that the lowest score and the highest score in the post-test is
higher than in the pre-test of both control class and experiment class. The writer gave pre-test first to the students before doing a treatment for
both control class and experiment class. And then he got the result that the average score of pre-test in both control class and experiment class were 41.76
and 44. After that, the writer did the treatment with teaching degree of comparison without using picture in control class and by using picture in
experiment class for three meetings. And then he got the result that the average score of post-test in both control class and experiment class were
53.44 and 61.92. It means that there was a significance difference of students’
achievement in pre-test and post-test after the writer conducted the treatment with teaching degree of comparison without using picture in control class and
by using picture in experiment class.

The table 4.2 above describes that the highest frequency is no. 4, where there are eight students who have gained score in interval 16
– 20. On the other hand, the lowest frequency is no. 1, where there are only three students
who have gained score in interval 1-5. Meanwhile, the frequency no. 2 and no. 3 are in the same rank, where there are seven students who had gained score in
interval 11-15 and in interval 16-20.
