B. RESEARCH FINDINGS
1. The Description of Data
The data were collected from students’ pre-test and post-test both two classes. The data which is obtained is described into two
tables. The students’ achievements in the experiment class were presented in the table 3.1 and the students’ achievements’ in the
control class were presented in table 3.2. Each table has four columns; the first column shows the number of students, the second and the
third column show pre-test and post-test scores, and the last column shows the gained scores which are obtained from post-test score is
subtracted pre-test score. The tables as follow:

highest score is 65 and the lowest score in the post-test is 60 and the highest score is 85. Therefore, it can be summarized that the lowest and highest score in post-
test is higher than pre-test scores.

The table above describes that the lowest score in pre-test is 45 and the highest score is 60 and the lowest score in the post-test is 55 and the highest score
is 75. Therefore, it can be summarized that the lowest and highest scores in post- test is higher than pre-test.
2. The Analysis of Data
Before the writer analyzed the data, the writer had calculated the scores into the statistic calculation. The writer used
�

formula to find the empirical evidence statistically and to make the testing of
hypothesis this research will easier. Prior the calculation of
�
�� �
, the writer made the calculation table to gain Mean and Deviation Standard from two variables, the
table as follow:
