the data of the research was statistically analyzed with independent sample test to compare the mean of two different data from different groups. In this case, the
researcher used statistical computation by using SPSS Statistical Program for Social Science.
The hypotheses are : H
a
: There is a 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
o
: There is no a significant influence of using common mistake game towards students‟ conditional sentence mastery at the first semester of the eleventh grade of
SMAN 1 Ambarawa Pringsewuin the academic year of 20162017. While the criteria acceptance or rejectionof hypotheses are:
H
o
is accepted if sig. α = 0,05 H

CHAPTER IV RESULT AND DISCUSSION
A. The Research Procedure
The research conducted in September 26
th
2016. Before conducting the research, the researcher asked the headmaster and the English teacher for permission at the
school. After getting the permission, the researcher conducted through the
following steps :
1. Determined the subject of the research, namely the students at the eleventh grade of SMAN 1 Ambarawa Pringsewu.
2. Designed the test which was the multiple choice test about conditional sentence type I for each of pre-test and post-test.
3. Determined the sample of the research by using cluster random sampling. 4. Held the try-out test to know the reliability and validity of the test, this test
was given to the students out of research sample, it was XI MIPA 1 5. After getting the valid and reliable items of the tests, the researcher gave
the valid and reliable items of pretest to sample. In this research the sample was XI MIPA 2 as an experimental class and XI MIPA 3 as a
control class. Holding the pre-test is to know the students‟ conditional
sentence mastery before they had treatment. 6. Analyzed the data gotten through the pre-test.
7. The treatment was conducted three times after the researcher gave the pretest to the sample. The researcher did the treatment of common
mistake game to the experimental class.
