87.31 564.02 The Data Of Experimental Class

From the Table 4.5 above, it can be seen that the student who got 70 were 2 students, the students who got 75 were 5 students, the students who got 80 were 7 students, and so on until the total number of frequency are 41 data.

2. The Data Of Controlled Class

The Table 4.6 below shows the students’ pre-test and post-test score of controlled class. There were 41 students in the control class variable Y.

Based on the table 4.2 above, it can be seen that the lowest score of pre-test in controlled class is 30 and the highest score is 80. The data shows that the lowest score of post-test in controlled class is 30 and the highest is 75. The result of pre-test and post-test on controlled class was calculated by using SPSS Version 22 with the steps as follows; analyze-description statistic-frequencies. Table 4.7 Data Description of Pre-test Result in Controlled Class It can be seen on the table 4.7 above that the total number of data in experimental class was 41. The mean score of pre-test in controlled class was 52.80. Mean is the average number of total score. The median score was 50.00. Median is the numerical value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. The mode score was 50. Mode is defined as an element that appears most frequently in a given set of elements. The highest score of pre-test in controlled class was 80 while the lowest was 25. Based on the table above, it can be formed a table of frequencies distribution as follows: Table 4.8 Frequency Distribution of Pre-test Result in Controlled Class The Table 4.8 above is a tool of presentation consisting serial numbers of pretest score and the frequency for each score in a table. It can be seen that the student who got 25 was 1 student, the students who got 30 were student, the student who got 35 was 1 student, and so on until the total number of frequency are 41 data. Table 4.9 Data Description of Post-test Result in Controlled Class Chart 4.1 It can be seen on the table 4.9 above that the total number of data in controlled class was 41. The mean score of post-test in experimental class was 58.05. The median score was 60.00. The most frequent score was 55. And the highest score of post-test in controlled class was 75 while the lowest was 30. Based on the table above, it can be formed a table of frequencies distribution as follows: Table 4.10 Frequency Distribution of Post-test Result in Controlled Class
