G. The Hypothesis of the Research
The hypothesis of the research is supposed as the temporary answer concerning to the problem that has been formulated in the research and it also
needs to validate the truth which using empirical data.
9
The hypothesis also means as the temporary conclusion about the relation between two variables
or more.
10
The hypothesis of this study will be formulated as follows:
a. Alternative hypothesis Ha
There is significant difference of students ’ achievement that are taught
degree of comparison by using pictures in experiment class and students’
achievement who are taught degree of comparison without using picture or through conventional teaching method in control class.
b. Null hypothesis Ho There is no significant difference of students
’ achievement that are taught degree of comparison by using pictures in experiment class and
students’ achievement who are taught degree of comparison without using picture or
through conventional teaching method in control class. Statistic hypothesis:
1. If t-test t t-table t
t
: there is significance difference. The alternative Hypothesis Ha is accepted and null Hypothesis H
is rejected. 2. If t-test t
t-table t
t
: there is no significance difference. The alternative Hypothesis Ha is rejected and null Hypothesis H
is accepted.

In this chapter, the writer discusses Research Findings which consists of four main topics; The Data Description, The Data Analysis, the Data
Interpretation, and the Test of Hypothesis.
1. The Data Description
After the writer conducted pre-test and post-test for both control class and experiment class, then he analyzed students
’ worksheet of both classes and found the total of right answer to be calculated into the score. After that, he
compared the result of the students’ pre-test and post test score, and then made
the table of the s tudents’ score from both control class and experiment class.
Table 4.1 shows the students’ score of both control class and experiment class that consists of
students’ number, pre-test score, post-test score and gained score from both classes.
