The Data of Experimental Class

Table 4.3 Table of Frequency distribution of Pre-test Result of Experimental Class Pre_test_Experimental_Class To provide additional description of the data distribution of pre-test in the experimental class, the histogram of frequency distribution is presented in figure 4.1 as follows: Figure 4.1 The Histogram of Pre-test Score in Experimental Class Frequency Valid 44 1 50 3 56 3 57 3 59 6 61 6 64 4 66 5 69 3 70 1 Total 35 From the table 4.3 and figure 4.1 above, the total number of students is 35 students. It shows that the students who got 44 and 70 was 1 student, the students who got 50, 56, 57 and 69 were three students for each, the students who got 59 and 61 were 6 students, the students who got 64 were 4 students, and the students who got 66 were 5 students. Apparently, from the curve of the histogram above, it shows that the data of pre-test in experimental class was normally distributed. Moreover, the post-test data description of experimental class can be presented as follows: Table 4.4 Data Description of Post-test Result of Experimental Class Statistics Post_test_Experimental_Class N Valid 35 Missing Mean 76.91 Median 77.00 Mode 76 a Minimum 66 Maximum 85 Sum 2692 a. Multiple modes exist. The smallest value is shown Based on the table 4.4 above, the writer has 35 post-test items from VIII-B as the experimental class. The mean score is 76.91. The median is 77.00 and the most frequent score is 76. Furthermore, the lowest and highest score are 66 and 85. The total of the score or the sum is 2692. A table frequency of post-test data from experimental could be made as follows: Table 4.5 Table of Frequency distribution of Post-test Result of Experimental Class Post_test_Experimental_Class Frequency Valid 66 1 69 2 72 3 74 4 76 6 77 6 79 1 80 3 81 5 83 3 85 1 Total 35 To provide additional description of the data distribution of post-test in the experimental class, the histogram of frequency distribution is presented in figure 4.2 as follows: Figure 4.2 The Histogram of Post-test Score in Experimental Class The table 4.5 and figure 4.2 above shows that the total of post-test items in experimental class is 35 students. There are two scores which become the most frequent score. They are 76 and 77. There are 6 students got each score. Then, there are 5 students who got 81 and 4 students got 74. Besides, 72, 80, and 83 were got by 3 students for each score. The next is 69 which was got by 2 students. The last is 1 student who got 66, 79, and 85. Because only 1 student who got each score, the scores become the less frequent in this class.

2. The Data of Controlled Class

The pre-test and post-test scores of contolled class is in the following table: Table 4.6 The Students’ Pre-test and Post-test Score of Controlled Class Students Number Pre-test Post-test Gained Score 1 60 78 18 2 64 73 9 3 63 71 8 4 66 73 7 5 57 66 9 6 48 68 20 7 63 66 3 8 67 77 10 9 63 66 3 10 67 77 10 11 52 59 7 12 59 73 14 13 55 68 13 14 63 68 5 15 52 73 21 16 59 62 3 17 60 63 3 18 63 64 1 19 66 77 11 20 67 76 9 21 60 64 4 22 66 78 12 23 59 68 9 24 57 71 14 25 66 78 12 26 60 62 2 27 65 71 6 28 55 66 11 29 70 80 10 30 63 68 5 31 60 71 11 32 57 73 16 33 67 77 10 34 60 66 6 35 60 68 8 36 67 71 4 Ƹ 2206 2530 324 Mean 61.27777778 70.27777778 9 Based on the table above, the pre-test and post-test score show that the lowest of pre-test score is 48 and the highest score is 70 with the mean 61.28. In addition, the lowest of post-test score is 59 and the highest score is 80 with the mean 70.28. The gained score of the controlled class is only 9. The further information of pre-test and post-test score of controlled class can be seen through tables and figure as follows: Table 4.7 Data Description of Pre-test Result of Controlled Class The table 4.7 above shows that the data from VIII-A as the controlled class consisted of 36 students. The mean score is 61.28. The median is 61.50 and the mode is 60. The score also has the minimum and maximum score. The minimum score is 48 and the maximum score is 70. The sum or the total of the score is 2206. A table frequency distribution could be made based on the table above. It is presented as follows: Table 4.8 Table of Frequency distribution of Pre-test Result of Controlled Class Pre_test_Controlled_Class Frequency Valid 48 1 52 2 55 2 57 3 59 3 60 7 63 6 64 1 65 1 66 4 67 5 Statistics Pre_test_Controlled_Class N Valid 36 Missing Mean 61.28 Median 61.50 Mode 60 Minimum 48 Maximum 70 Sum 2206 70 1 Total 36 To provide additional description of the data distribution of post-test in the experimental class, the histogram of frequency distribution is presented in figure 4.3 as follows: Figure 4.3 The Histogram of Pre-test Score in Controlled Class The table 4.8 and figure 4.3 above shows that the most frequent score which was got by 7 students is 60. Then, there are 6 students got 63, 5 students got 66, and 4 students got 66. Moreover, 57 and 59 were got by 3 students for each score. The next, 2 students got 52 and 55. The last, 48, 64, 65, and 70 become the less frequent score because only 1 student got each score. The total of the students in the controlled class is 36. Furthermore, the description of post-test score in the controlled class can be presented as follows:
