CHAPTER IV RESEARCH FINDING
This chapter presents the findings of the study. It will present the data description, the data analysis, the testing hypothesis and the data interpretation.
A. Data Description
This section will describe the scores of both the experimental class and the controlled class. The pre-test scores will be firstly presented and then the post-
test scores and the last are gained scores.
1. The Pre-test Scores
Table 4.1 reports the pre-test scores of the experimental class and the pre- test scores of the controlled class. There are 35 students in the experimental class
and 35 students in the controlled class.

The scores processed from student’s answer sheet
The above table is the score of pre-test for the experimental class and the controlled class. The test was given in the first meeting before the treatment. The
lowest score in pre-test of the experimental class is 25 and the controlled class is 20. The median score in pre-test of experimental class is 60 and the controlled
class is 45. Besides, the highest score of the experimental class is 90 and the controlled class is 75. Meanwhile, the mode score in pre-test of experimental class
is 65 and the controlled class is 45. Furthermore, the mean score of the experimental class is 62.57 and the controlled class is 50.14. In order to check
whether the scores of pre-test in both the experimental and the controlled class are statistically different, t-test was performed in the data analysis.
2. The Post-test Scores
Table 4.2 reports the post-test scores of the experimental class and the controlled class. There are 35 students in the experimental class and 35 students in
the controlled class.

The scores processed from student’s answer sheet
In the post test, the lowest score of the experimental class is 70 and the controlled class is 40. Meanwhile, the medium score of the experimental class is
85 and the controlled class is 65. And then, the highest score of post-test in the experimental class is 95 and the controlled class is 80. Besides, the mode score of
post-test in the experimental class is 95 and the control class is 75. Meanwhile, the mean score of post-test in the experimental class is 97.71 and the controlled class
is 67.42. The writer will do t-test to see whether the experimental class and the controlled class differ in their post-test.
