Based on the Table 4.2, it could be seen the lowest and the highest score of the controlled class consists of 37 students. The lowest score in pre-test was 34
and the highest score was 80. The data showed in the post-test that the lowest score was 44 and the highest was 85.
B. Analysis of Data and Hypothesis Testing
1. Results of Pre-test of Experimental and Controlled Class
The result of pre-test of experimental and controlled class based on SPSS 22 version software was gained from the steps as follows: Analyze Description

a. Multiple modes exist. The smallest value is shown
Table 4.3 showed that the data of X MIPA 1 as the experimental class consisted of 37 students. The total of all data which was divided with the number
of data determined as mean score from the experimental class was 61.24. Median score was 65.00. The 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 is defined as the element that appears most frequently in a given set of
elements. The mode score from the table was 47. The set of scores constituted a population determined a variance score was 210.967. The highest score of the
experimental class was 90 and the lowest was 34. The sum gained from the total scores was 2266.
According to the table, it could be made a table of frequency distribution which is presented as follows:
