CHAPTER IV RESEARCH FINDINGS AND INTERPRETATION
A. Description of the Data
The data from students’ pre-test and post-test was collected in this research as the main instrument. The pre-test was administered before the treatment is
given to the experimental class and control class; meanwhile the post-test was administered after the treatment is given to the experimental class and control
class. The data that can be used in this research is 39 students’ pre-test and post- test scores from experimental class and 39 students’ pre-test and post-test scores
from control class. It was due to one experimental class student’s absence in pre- test and one control class student’s absence in post-test. Table 4.1, 4.2, and 4.3
present the experimental class students’ pre-test score, post-test score, and gained score. Here are the descriptions:
1. Pre-test Score
In this part, the data of the pre-test score of experimental class and control class is provided. These are the description:

Mean 74.36
Mean 69.62
Based on Table 4.1, we can see that in experimental class, the highest pre- test score is 85 while the lowest pre-test score is 50. On the other hand, in the
control class, the highest pre-test score is 90 while the lowest pre-test score is 45. Moreover, in the experimental class, the average score or mean is 74.36, the mode
is 75, and the median is 75.00. On the other hand, in the control class, the average score or mean is 69.92, the mode is 75, and the median is 70.00
From the students’ pre-test score mean, median, and mode, it can be assumed that students from the experimental class performed better than students
from the control class in the pre-test. This assumption was tested using t-test in the next section.
2. Post-test Score
In this part, the data of the post-test score of experimental class and control
class is provided. These are the description: Table 4.2
