64 score, there were seven students who got 68 score, there were five students who got 72 score, and onlyone students got 76 score.

While for the statistics of the result of the post test of XI MIPA 3 as the control class it can be seen in Table 12. From Table 12, it can be seen that the mean score
was 65. The maximum score was 76. The minimum score was 56. The median score was 64. The mode score was 64.
D. Result of Data Analysis 1. Fulfillments of the Assumption
a. Result of Normality Test
The researcher did this normality test to know whether the data has normal distribution or not. The hypothesis for the normality test are formulated as
follow: H
: the data are normally distributed
H
a
: the data are not normally distributed
While the criteria for the normality test are as follow : H
is accepted if Sig p
value
α = 0.05
Ha is accepted if Sig p
value
α = 0.05

Based on the Table 13, it can be seen that Sig p
value
for experimental class was 0.001 and Sig. p
value
for control class was 0.000 and α = 0.05.It means thatSig
p
value
α and H
o
is rejected. The conclusion is the data were not in the normal distribution.
b. The Result of Homogeneity Test
The researcher did this homogeneity test to know whether the data is homogeneous or not.The hypotheses for the homogeneity test are formulated as
follows : H
= The variance of the data is homogenous H
a
= The variance of the data is not homogenous
While the criteria for the homogeneity test are as follows : H
is accepted if Sig p
value
α = 0.05 Ha is accepted if Sig p
value
α = 0.05

Based on the Table 14, it can be seen that Sig p
value
based on mean was 0.007, and α = 0.05. It means thatSig p
value
α and H is rejected. The conclusion is that
the datahave not same variance or not homogenous.
c. The Result of Hypothetical Test
After the researcher knew that the data was not normal and homogeneous, the data was analyzed by using Mann Whitneytest in order to know the significance of the
treatment effect. The hypotheses are:
H
o
: There is no significant influence of using common mistake game towards students‟ conditional sentence mastery at the first semester of the eleventh grade
of SMAN 1 Ambarawa Pringsewu in the academic year of 20162017. H
a
: There is significant influence of using common mistake game towards students‟ conditional sentence mastery at the first semester of the eleventh grade
of SMAN 1 Ambarawa Pringsewu in the academic year of 20162017. While the criteria for acceptance and rejection of the hypothesis are:
