B. Hypothesis Test
1. Test of Requirement Analysis
Test of requirement analysis was performed before hypothesis testing, both of which will use statistical parametric or statistical non-parametric.
Test of requirement analysis was done by two tests, that are normality test and homogeneity test. Results of test of requirement analysis in this
research are as follows:
a. Normality Test
Normality test aims to determine the normalcy degree of data distribution. Normality test is done on the data of learning outcomes
and student Identity Style. To determine whether the data is normally distributed or not can be seen in Asymp. Sig 2-tailed. If the value is
less than the significance level of 0,05; then the data is not normally distributed. Conversely, if the value is more than the significance level
of 0,05; then the data is normally distributed. Normality test data using SPSS 19.00 for Windows. The normality test result of student identity
style can be seen in the following table:
Table 24. Summary of Normality Test of Student Identity Styles Experimental group
Control Group Identity Style
Identity Style
Statistic 0,051
0,117 Source: Primary Data are Processed
The experimental group gained the Statistic value in amount of 0,051; while the control group gained the Statistic value in amount of
0,117. Then the value of each variables in two groups is normal
distribution because the variables in both groups have statistic value which is greater than the significance level of 0,05.
Whereas the normality test result of student learning outcomes can be seen in the following table:

The experimental group obtained the value of Asymp. Sig 2- tailed in amount of 0,713 for the pretest and 0,766 for the posttest,
while the control group gained the value of Asymp. Sig 2-tailed in amount of 0,910 for the pretest and 0,497 for the posttest. Then the
value of each variable on the two groups is normal distribution because the value of the variables in both groups had Asymp. Sig 2-tailed is
greater than the significance level of 0,05.
b. Homogeneity Test
