Table 4.4 was tool of presentation consisting of columns and rows and there were numbers which describe the division and the percentage of frequency
distribution. Results gained from a pre-test in class X MIPA 5 as the controlled class of
this research were presented in a table below:

Table 4.5 showed that the data of X MIPA 5 as the controlled class was 37 students. The total of all data which was divided with the number of data
determined as mean score from the controlled class was 52.46. Median score was 49.00. 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 39. The set of scores constituted a population determined a variance score was 195.755. The highest score of the controlled
class was 80 and the lowest is 34. The sum gained from the total scores was 1941.

Table 4.7 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 81.03. Median score was 80.00. The mode score from the table was also 80.00. The set of scores
constituted a population determined a variance score was 44.416. The highest score of the experimental class was 90 and the lowest was 62. The sum gained
from the total scores was 2998. According to the table, it could be made a table of frequency distribution

Before the writer calculated the value of t-test to look at the hypothesis, the writer had to analyze the normality and homogeneity of the data. The examination
of normality was needed to know whether the data had been normally distributed. Then, after getting the normality, the next step was calculating the homogeneity of
data. It was proposed to look at whether the data was homogeneous or heterogeneous.
