Values in table 4.2 above are the students’ pre-test score in X IPA 2. The table shows that 1 student gained score 40 (9.1%), 1 student gained score 44 (9.1%), 1 student gained score 48 (9.1%), 1 student gained score 52 (9.1%), 3 students gained score 60 (27.3%), 1 student gained score 64 (9.1%), 1 student gained score 68 (9.1%), 1 student gained score 72 (9.1%), 1 student gained score 76 (9.1%).
The histogram below can show the data in more detail:

From the figures 4.1, it can be seen that M = 58.55 and SD
= 11.492. To determine the category of students’ reading comprehension was good, medium, or low, the researcher grouped scores as follows:
1. More than M + 1.SD (58.2 + 11.492 = 69.692) was categorized into good.
2. Between M – 1.SD (58.2 – 11.492 = 46.708) to M + 1.SD (58.2 + 11.492 = 9.692) was categorized as medium.
3. Less than M - 1.SD () was categorized as low.
Thus, it can be seen that the scores which are more than 69.692 was considered into good, the scores between 46.708 – 69.692 was categorized into medium, while the score less than 46.702 was categorized into low. The categorization can be seen in the following table:

2 Between 47 - 70 7 63.60% Medium
3 Less than 47 2 18.20% Low
Total 11 100%
From the table above, it could be seen that the score of students’ reading comprehension of experimental class in pre-
test showed that 18.20% in the good category, 63.60% in the medium category, and 18.20% in the low category.

From the figures 4.2, it can be seen that M = 82.18 and SD
= 7.454. To determine the category of students’ reading comprehension was good, medium, or low, the researcher grouped scores as follows:
1. More than M + 1.SD (82.18 + 7.454) was categorized into good.
2. Between M – 1.SD (82.18 – 7.454) to M + 1.SD (82.18 + 7.454) was categorized as medium.
3. Less than M - 1.SD (82.18 – 7.454) was categorized as low.
Thus, it can be seen that the scores which are more than 89.634 was considered into good, the scores between 89.634 – 74.726 was categorized into medium, while the score less than 74.726 was categorized into low. The categorization can be seen in the following table:

From the table above, it could be seen that the score of students’ reading comprehension of experimental class in post- test showed that 18.10% in the good category, 81.90% in the medium category, and 0% in the low category.
b. The Results of Students’ Test Score in Control Class
Following are the results of students’ tests for the control class:
1) The table below showed the students’ writing results before and after the students were taught by conventional method. The students’ score were:

According to the table 4.7, the highest pre-test score is 80, while the lowest pre-test score is 60. In Post-Test, the highest score is 76, while the lowest score is 52. The total score of Pre-
test is 748 and the mean score is 68, the total score of Post-Test is 704 and the mean score is 64.18.

Values in table 4.8 above are the students’ pre-test score in X IPA 1. The table shows that 3 students gained score 60 (27.3%), 1 student gained score 64 (9.1%), 3 students gained score 68 (27.3%), 2 students gained score 72 (18.2%), 1 student gained score 76 (9.1%), 1 student gained score 80 (9.1%).
The histogram below can show the data in more detail:

From the figures 4.3, it can be seen that M = 68 and SD = 6.693. To determine the category of students’ reading comprehension was good, medium, or low, the researcher grouped scores as follows:
1. More than M + 1.SD (68 + 6.693) was categorized into good.
2. Between M - 1.SD (68 - 6.693) to M + 1.SD (68 + 6.693) was categorized as medium.
3. Less than M - 1.SD (68 - 6.693) was categorized as low.
Thus, it can be seen that the scores which are more than 74.693 was considered into good, the scores between 61.307 – 74.693 was categorized into medium, while the score less than 61.307 was categorized into low. The categorization can be seen in the following table:

From the figures 4.4, it can be seen that M = 64.18 and SD
= 7.821. To determine the category of students’ reading comprehension was good, medium, or low, the researcher grouped scores as follows:
1. More than M + 1.SD (64.18 + 7.821) was categorized into good.
2. Between M – 1.SD (64.18 – 7.821) to M + 1.SD (64.18 + 7.281) was categorized as medium.
3. Less than M - 1.SD (64.18 – 7.821) was categorized as low.
Thus, it can be seen that the scores which are more than 72.001 was considered into good, the scores between 56.359 – 72.001 was categorized into medium, while the score less than 56.359 was categorized into low. The categorization can be seen in the following table:

From the table above, it could be seen that the score of students’ reading comprehension of control class in post-test
showed that 9% in the good category, 82% in the medium category, and 9% in the low category.
