3.5.2 Interview
In this research, an interview was conducted to get the supporting data. The interview was done with the English teacher of the eighth grade in SMP
Negeri 1 Silo. It was intended to get information about the background of reading comprehension. The researcher used a list of questions that were asked to the
teacher while interviewing the teacher. The interview covered the information about the English curriculum used in the school, the reading materials, the
teacher’s technique in teaching reading, and the reading tasks that are usually given to the students. It was also about the students
’ difficulty in reading comprehension of a text. The interview was carried out when the researcher did
the preliminary study on December, 13
th
2014.
3.5.3 Documentation
Documentation was another method to get the supporting data. The documents needed in this research consisted of the names of the respondents in
the eighth grade of SMP Negeri 1 Silo Jember, both the experimental and the control students in the form of the list of the names of the respondents and the
previous English scores of the students.
3.6 Data Analysis Method
In this research, the researcher used SPSS to analyze the data of the result of the reading posttest. Here, the independent sample t-test was used to know
whether there was a difference between the mean of the two groups from different samples. The two groups that were compared were the experimental group which
was taught reading by skimming and scanning techniques and the control group which was taught reading by using discussion technique.
In the Independent Sample t-test, there are two parts. They are test variable and grouping variable. Here is the description of the two variables:
Test Variable :
The students’ Reading Comprehension
Achievement Grouping Variable
: The experimental and the control groups. There were some steps to analyze the data by using the Independent
Sample t-test as follows: 1.
Open the data file which has inserted into SPSS Data Editor. 2.
From the analyzing menu, choose sub-menu Compare Means, choose Independent Sample t-test. Then, appear a dialogue box. Fill it with the
following description: a.
Test Variable is entered by the variable of the Students’ Reading Comprehension Achievement.
b. Grouping Variable is entered by the variable of class the experimental
and the control groups c.

According to SPSS data output, there are two stages of analysis in the Independent Sample t-test to know whether or not there is a significant effect of
using skimming and scanning techniques on the eighth grade students’ reading comprehension. They are the test of Equality of Variances F
test
and the test of Equality of Mean Score T
test
. The following are more detail explanations about the two tests:
1. The Equality of Variances F
test
Hypothesis: H
= The variances of the two groups are identically the same H
1
= The variances of the two groups are not the same The criteria of taking decision for F
test
a. H
is accepted and H
1
is rejected if the significant number is the same or higher than 0.05. It means that the variances of the two groups the
experimental group and the control group are the same.
b. H
is rejected and H
1
is accepted if the significant number is lower than 0.05. It means that the variances of the two groups the experimental group
and the control group are not the same.
2. The Equality of Mean Score T
test
Hypothesis: H
= The mean score of the two classes are the same. H
1
= The mean score of the two classes are not the same The criteria of taking decision for T
test
a. H
is accepted and H
1
is rejected if the significant number is the same or higher than 0.05. It means that the mean scores of the two groups the
experimental group and the control group are the same. b.
H is rejected and H
1
is accepted if the significant number is lower than 0.05. It means that the mean scores of the two groups the experimental
group and the control group are not the same.

The treatment was given to the experimental group, that was teaching reading by using skimming and scanning techniques. Meanwhile, the control
group was taught reading by using the conventional technique used by the English teacher, that was discussion technique. The experimental group was given the
treatment twice. The schedule of administering the activities is presented in Table 4.2 below:
