and post-test in experimental class is 9.70 , with the highest student’s gained score
is 16 and the lowest student’s gained score is -7.

Based on the data from controlled class, the data shows that the highest score of pre-test in the experimental class is 71 and the lowest score of pre-test is 54.
Besides that, the mean score of pre-test in experimental class is 61.35. From the frequency distribution table of pre-test result from experimental class, it can be
seen that from 20 students in controlled class, there are 5 students had score
between 54 – 59, 13 student had score between 60 – 65 and 1 student had score
between 66 – 70 and 1 student had score 71
It also shows that the mean score of post-test in controlled class is 64.80 with 72 as the highest score and 54 as the lowest score. Then, the frequency
distribution table of post-test result also shows that there are 1 student had score between 50
– 55, 4 students had score between 55 – 60, 7 students had score between 61
– 65, 5 students had score between 66 – 70 and 3 students had score 71 - 75
In addition, the calculation also shows that the total of gained score of pre-test and post-test in controlled class is 75 and the mean of gained score of pre-test and
post-test in controlled class is 3.75 , with the highest student’s gained score is 11
and the lowest student’s gained score is -8.
B. Data Analysis
1. Normality Test of the Data
The result of normality test on both experimental and controlled class’ pre- test and post-test was gained from Lilliefors test using SPSS 22. This test is used
to determine whether the distribution of the data from the sample is normal. If the normality is more than the level of significance
α 0.05, scores will be normally distributed.
The following table was the results of normality test of the experimental and controlled class’ pre-test:
