CHAPTER III METHOD OF THE ANALYSIS
I will conduct some methods to complete this thesis and to get some information which related to this thesis. I conduct two kinds of research: library
research and field research. In the library research, I read some books and select some which are concerned with the study to gain the information and make them as the
references.
3.1 Location and Instrument Research
This research was conducted at Yayasan Perguruan Indonesia Membangun YAPIM Mabar on Jl. Mangaan VII, Ling. 16. Mabar. This location was chosen
because the same research has never been conducted there. I used some instruments in collecting the data namely television, DVD
cassette, head set, white board, and board marker.
3.2 Population and Sample
In reminding that there is the limitation of time, energy and funds, not all of the eleventh students become the objective research. I set 50 of the students from
each the class become the respondents in order the conclusion of that test is accurate. The reason for taking the number based on Arikunto’s idea 1993:120 says that if the
population consists of a large number, the sample can be taken from 10-15 or 20-25 or more, it depends on the ability of the researcher by considering her time,
energy and funds. Each of the class is consist of 40 students. There are two classes; it
Universitas Sumatera Utara
means that the whole of the eleventh students are 80 students. Fifty percent of the students from each class are:
50 x 40 students = 20 students
100 They will be chosen based on the attendant list. So, the numbers of the
students who will be the respondents are 2 x 20 = 40 students. It means that the percentage of the sample is:
40 x 100 = 50.
80 The sample will be taken randomly considering what Gay 1987:10 says that
random sampling is the best single way to obtain a representative sample. The reason why the sample is the eleventh students because they have much
time and the opportunity to be tested than in the twelfth students for who have focused on National Final Examination or Ujian Akhir Nasional UAN.
3.3 Technique of Analyzing Data
In order to find out the ability of the eleventh year students in listening comprehension, I use the criteria proposed by the Department of Education and
culture Diknas 1990:10. The criteria after translated to be some criteria as described as follow:
Universitas Sumatera Utara
SCORE CATEGORY
90-100 Excellent 80-89 Very
good 70-79 Good
60-69 More than fair
50-59 Fair 40-49 Almost
fair 30-39 Lack
20-29 Very Lack
10-19 Bad 0-9 Worst
I will describe the score of the eleventh year students on Pre-Test and Post-Test with the formulation as follow:
100 2
1 x
N N
P =
Where: P = Percentage
N1 = Amount of able students
N2 = Amount of a whole students
Example:
Universitas Sumatera Utara
Score N1 N2
Percentage
90 10 40
25 70 10
40 25
50 15 40
37.5 40 5
40 12.5
Mean of the class from the total score can get from the formulation below:
N SS
X =
Where : X = Mean of the all students’ score
SS = The total sum of the able students’ scores
N = Amount of whole students
The average of the scores can be seen from the table below:
Score N SS
90 10 900
70 10 700
50 15 750
40 5 200
Total 40
2550 X
63.75
Universitas Sumatera Utara
Therefore, the average from the total score of the score is 63.75. The round off upwards is 64. The category for the score is more than fair.
