The coefficient of correlation from the computation above is 0,314. The result is greater than it is required in the product moment table for 40
sample N=40. The value of
r
XY required for at 1 level of significance is 0,257. Therefore the test instrument can be considered valid.
3.4.3 Practicality
The test is called to be practical if it is economical, easily administered, easily scored, and easily interpreted. Waluyo, 1989:53-54
3.5 The Technique of Analyzing the Data.
After the data have been obtained, they requireto be analyzed. In analyzing the data, the writer uses the percentage. It is used to know how
many percent the studentsmastery of the test. The first step in treating the data is scoring. In this case, the data are the
result of the students test. In scoring the data, each item gets 1 points. The number of the item is100, so the total is 100 which is divided by 10. For
example: a student gets right answer 75, it becomes 75 x 1 = 7510 = 7,5. So his score is 7,5.
The next analysis is description of the data into formula. S =
100 x
N R
Notes : S : The students mastery in .
R : The students score.
29
N : The number of the test. The next step is that the writer classifies the scores into two parts,
quantitative scores and qualitative scores. In this case, the writer uses the category proposed by Suharsimi Arikunto 1993:294. Which can be seen
below: No.
Quantitative scores Qualitative scores
1. 2.
3. 4.
5. 8.1 – 10
6.6 – 8.0 5.6 – 6.5
4.1 – 5.5 0 – 4.0
Very Good Good
Fair Poor
Fail
The final analysis is counting the sum of the students who get very good, fair, poor, or fail categories.

CHAPTER IV THE RESULT OF THE STUDY
4.1 The Preparation of the Research
The writer commits some preparations before getting the data. The steps are as follows :
a He choose the research location in SMU, because he has friend as a
teacher in SMUN I Wiradesa. So it is easy to deal with everything concerning it.
b He got the data by using a test, so he can plan the test first before
making a test instrument. c
The other preparation is that the writer took the research sample by using the proportional random sampling method.
This way has been elaborated in previous chapter.
4.2 Constructing the Test
The material to be used in getting the data was taken from Understanding and Using English Grammar in Use by Betty Azhar S.
and English Grammar in Use by Raymond Murphy.
The total number of the test items are 100 that consists of conjunctions but, and, or, before,
and after and those items can be described as follows :
31
a. Conjunction but.
It consists of 22 items, they are number 1, 5, 13, 14, 23, 29, 31, 32, 34, 35, 40, 45, 51, 54, 56, 58, 62, 65, 66, 72, 73, 76.
b. Conjunction and.
It consists of 31 items, they are number 2, 3, 8, 11, 24, 25, 30, 33, 36, 38, 39, 50, 53, 55, 59, 61, 68, 69, 70, 71, 77, 78, 79, 89, 90, 91, 92, 93, 96, 97, 100.
c. Conjunction or.
It consists of 23 items, they are number 16, 18, 20, 21, 22, 26, 27, 28, 37, 41, 42, 60, 75, 80, 81, 82, 83, 84, 86, 87, 88, 98, 99.
d. Conjunction before.
It consists of 6 items, they are number 6, 10, 12, 15, 17, 35. e.
Conjunction after. It consists of 18 items, they are number 4, 7, 9, 19, 43, 44, 46, 47, 48, 49, 52,
57, 63, 64, 67, 74, 94, 95. The data that will be show the result of the study must be true and accurate.
As started before, the writer uses a test in collecting the data.
