The table shows the results pre-test and post-test scores from controlled class. The table shows that the mean score of pre-test is 69.06
and the mean score of post-test is 72.26. Moreover, the highest score of pre-test is 88 meanwhile the lowest score of pre-test is 52. Then, the table
also shows that the highest score of post-test is 88 whereas the lowest score of post-test is 56.

Data Analysis
After the writer had got student’s scores of pre – test and post – test from both experimental and control classes, she will analyze by using t-
test formula to test the hypotheses that the writer proposed before. Before calculating them by using t-test formula, she tested normality and
homogeneity test after she got students ’ score in pre-test and post-test of
degrees of comparison by using SPSS 18.
1. Normality Test of Pre-test and Post-test
Based on Lilifors from sample n 30 with significance level α= 0.05
a. If the value p significant α =0.05 it means that the sample
from the population, 69.7. H
o
was accepted and H
1
was rejected normal distribution.
b. If the value p significant α =0.05
it
means H
o
was rejected and H
1
was accepted not normal distribution

Based on table 4.3 above, the writer compared of normality in pre-test of experimental class was 0.150 with significant 0.05. It
concluded the result pre-test of experimental was higher than the significant 0.05; 0.150 0.05. Furthermore, the normality in pre-
test of control class was 0.170 with significant 0.05. The result pre- test of control class was higher than the significant 0.05; 0.170
0.05. Therefore, the data pre-test of experimental and control classes was normal distribution.

Based on table 4.4 above, the writer compared of normality in post-test of experimental class was 0.074 with significant 0.05. It
concluded the result post-test of experimental was higher than the significant 0.05; 0.074 0.05. Furthermore, the normality in post-
test of control class was 0.061 with significant 0.05. The result post- test of control class was higher than the significant 0.05; 0.061
0.05. Therefore, the data post-test of experimental and control class were normal distribution.
2. Homogeneity Test of Pre-test and Post-test
The writer tested homogeneity test after she got students ’ score of
degrees of comparison in experimental and control class Pre-test and Post-test of degrees of comparison by using SPSS 18.

Based on table 4.5 above, the result of homogeneity test pre-test of experimental and controlled class was higher than the significant
0.05; 0.285 0.05 it means that the data was homogenous.

The result of homogeneity test post-test from the table 4.6 described for experimental and control class was higher than the
significant 0.05; 0.450 0.05 it means that the data were homogenous.
