The Result of Control Group
2. The Result of Control Group
In this case the data of control group consisted of the pre-test scores, the post-test score, and the comparison between both of them. The data of the pre-test score and post-test score of the control group are explained as follows:
Table 4.4 The Comparison of Pre-test and Post-test Score of
Control Group

40 Very Poor
Deviation Standard
For the table of pre-test above, it can bee seen that there were 2 students (10%) whose score was classified in the very poor category.
There were 4 students (20%) whose score was classified in the poor category. There were 4 students (20%) whose score was classified in the fair category. There were 8 students (40%) whose score was classified in the very category. There were 1 students (5%) whose score was classified in the very good category. Meanwhile for the table of post-test, it can bee seen that there were 6 students (30%) whose score was classified in the fair category. There were 7 students (35%) whose score was classified in the good category. There were 7 students (35%) whose score was classified in the very good category. The process to find mean, standard deviation, and standard error are available in appendix 7.
a. The Result of Pre-test
The pre-test score of control group were present in the following table:

Based on the data above. It can be seen that the student‟s highest score was 90 and the student‟s lowest score was 40. To determine the range of
score, the class interval and interval temporary, the writer calculated using formula s follows:
The highest score (H)
The lowest score (L)
The range score (R)
= H-L + 1 = 90-40 + 1 = 50 + 1 = 51
The class interval (K)
= 1 + 3,3 log n = 1 + 3,3 log (20) = 1 + 3,3 .1,3 = 1 + 4,29 = 5,29 =5
Interval of Temporary (I) = R/K
So, the range of score was 51, the class interval was 5 and the interval of temporary was 10. It was presented using frequency distribution in the following table:

The distribution of student‟s predicated in pre-test score of control group can also be seen in following figure:
51-61 40-50

Figure 4.3 The Frequency Distribution of Pre-test of the Control
Group
The table and figure above showed the pre-test score students in control group. It can be seen that there were 2 students who got score 40-
50. There were 6 students who got score 51-61. There were 9 students who got score 62-72. There were 2 students who got score 73-83. There were 1 students who got score 84-94.
b. The Result of Post-test
The pre-test score of control group were present in the following table:

B05
Based on the data above. It can be seen that the student‟s highest score was 95 and the student‟s lowest score was 60. To determine the range of score, the class interval and interval temporary, the writer calculated using formula s follows:
The highest score (H)
The lowest score (L)
The range score (R)
= H-L + 1 = 95-60+ 1 = 35 + 1 = 36
The class interval (K)
= 1 + 3,3 log n = 1 + 3,3 log (20) = 1 + 3,3 .1,3 = 1 + 4,29 = 5,29 =5
Interval of Temporary (I) = R/K
So, the range of score was 36, the class interval was 5 and the interval of temporary was 7. It was presented using frequency distribution in the following table:

The distribution of student‟s predicated in pre-test score of control group can also be seen in following figure:

The table and figure above showed the pre-test score students in control group. It can be seen that there were 5 students who got score 60-
67. There were 7 students who got score 68-75. There were 5 students who got score 76-83. There were 1 students who got score 84-91. There were 1 students who got score 92-99.
