The table 4.9 shows that the mean of the 30 students is 71. The median score from the table is 70. The mode score is 65. The
set of the score constitute a population determine as variance score is 50.690. Standard deviation is a quantity calculated to indicate the
extent of deviation for a group as a whole and it is 7.1206. Then the sum gained from the total score is 2130.

Data Analysis 1.
Normality test
a Pre-test Normality test The normality test in this research use Saphiro Wilk because the
participant 50. The data was analysed by using SPSS v.22 for
windows with the criteria 0.05. The result of normality test of
the data are presented as follow:

a. Lilliefors Significance Correction
From the table 4.11 above, it can be seen that the significance of the normality pre-test score in experimental class is 0.207. It can be
calculated that the data are normally distributed because 0.207 0.05. Then, the significance of pre-test score in controlled class is
0.270. Therefore, the data are normally distributed because 0.270 0.05. So the writer can conclude that the result in both of
experimental and controlled class are normally distributed.
b Post-test Normality test The normality in this test used Saphiro Wilk. The data was
analysed by using SPSS v.22 for windows. Then the result of normality test of the data are presented as follow:
Table 4.12 Normality Post-test result Between Experimental and
Controlled Class
From the table 4.12 above, shows that the significance of the normality post-test score in experimental class is 0.175. It means
that the data are normally distributed because 0.207 0.05.
Moreover, the significance of post-test score in controlled class is 0.057. By meaning the data are normally distributed because 0.057
0.05. Then the writer conclude that the result in both of experimental and controlled class are normally distributed.
