Based on the liliefors table. It is found that L
critical
for 30 students with α = 0.05 is 0.161. Therefore, it can be concluded that the data above are in the normal
distribution because L
observed
0.121 was L
critical
0.161 in control class and L
observed
0.136 was L
critical
0.161 in experimental class.
While the score of normality test of post-test of both control and experimental class were as follows:
L
observed
post-test of control class was 0.111 L
observed
post-test of experimental class was 0.142

5. The Result of HomogeneityTest
Homogeneity test is used to know wheter the variance of the data is homogenous or not.
Hypothesis formula: H
o
= The variance of the data homogenous H
a
= The variance of the data not homogenous
Criteria for the test are as follows: H
o
is accepted if F
observed
F
critical
Ha is accepted if F
observed
F
critical
From the data gained, the homogeneity test of control class was 1.50 and experimental class was 1.34 the result above was to be consulted to fisher table,
it was found that F-critical of 0.05 29.29 = 1.84 .The data came from homogenous data provided Fobserved Fcritical. It means that the variance of the
data were homogenous. See appendix 19
6. The Result of Hypothetical Test
The result of the T-test was 3.7 while the df number of sample from both control and experimental classes subtracted by 2 was 58. So that the result of level of significant
0.05 is 1.67. If t
observed
t
critical
Ha was accepted because 3.7 1.67. So in this case, Ha was accepted. Then, it could be assumed that there was influence of using
Fan-N-Pick technique towards students’ vocabulary mastery. See appendix 21.
Then it could be assumed that there was significant influence of using Fan-N-Pick technique toward students’ vocabulary.
