6. Analyzing the results of reading posttest scores by using Independent
Sample t-test with SPSS Statistical Package for Social Science to compare the result of the reading scores between the experimental group
and the control group. The results were compared to see whether or not there was a significant effect of using skimming and scanning techniques
on the students’ reading comprehension. 7.
Drawing a conclusion from the result of the data analysis to answer the research problem.
3.2 Area Determination Method
The area of this research was SMP Negeri 1 Silo Jember. This school was chosen by using the purposive method. Singh 2006:213 states that in the
purposive method, the data were collected by the sense of purpose. The reason of choosing this school was because the English teacher of the eighth grade never
applies skimming and scanning techniques in teaching reading. The second reason was both the Headmaster and the English teacher gave permission to the
researcher to conduct this experimental research in that school.
3.3 Respondent Determination Method
In this research, cluster random sampling by lottery was used to determine the respondents of the experimental group and the control group since the
population was homogenous. It was proven by analyzing the students’ previous
midterm test score by using ANOVA. The method used by the researcher was cluster random sampling with the reason that the headmaster of the school did not
permit the researcher to take the sample from every class. According to Singh 2006:89, the units of sample in cluster sampling contain groups of elements
clusters instead of individual members or items in the population. The population of this research was all of the eighth students of SMP
Negeri 1 Silo Jember in the 20142015 academic year. There are five classes of the eighth grade students of SMP Negeri 1 Silo Jember in the 20142015
academic year. Each class consists of thirty four up to thirty six students. Based
on the eighth students’ attendance list, there are 36 students in VIII A, 36 students
in VIII B, 34 students in VIII C, 35 students in VIII D and 34 students in VIII E. So, there are 175 students of the eighth grade classes. In this research, intact group
comparison was used because the two classes as the experimental and the control groups were chosen randomly. The researcher decided to take one class as the
experimental group and one class as the control group as the respondents of this research.
