E. Technique of Data Collection
This study employed two different tests for getting the data. The tests used in this study were collocation knowledge test and reading comprehension test. The
tests were conducted to measure the students’ collocation knowledge and their reading comprehension. A multiple-choice test type was used in designing both
tests and each test consisted of 20 items. The assessment guideline for assessing the tests was number of true score was divided by total number of the test and was
multiplied by 100. In collecting the data, the first test conducted in this study was collocation test for collecting data of students’ collocation knowledge. Afterward,
reading comprehension test was conducted for collecting data of students’ reading comprehension test.
F. Technique of Data Analysis
For analyzing the data, the study used a formula of Pearson Product- Moment Correlation. Pearson product-moment correlation can be used to analyze
data which is collected from the result of the two variables measurement in interval scale.

The formula used for finding the number of correlation, as follows:

r =
In which: N
= the number of respondent X
= the student’s score in collocation knowledge Y
= the student’s score in reading comprehension ΣX
= the sum of collocation knowledge score ΣY
= the sum of reading comprehension score ΣX

= the sum of squares of collocation knowledge score ΣY

= the sum of squares of reading comprehension score ΣX
2
= the squares of the sum of collocation knowledge score ΣY

= the squares of the sum of reading comprehension score ΣXY = the sum multiple of collocation knowledge score and reading
comprehension score Then, the contribution of the independent variable x towards the dependent
variable y was investigated through the determination coefficient r

as follows:

= value of the squared correlation coefficient Moreover, after getting the r score, the significance between two variables
was tested to know the correlation between variable X and variable Y. The formula of the significance test is:

r = value of correlation coefficient
n = number of sample
After getting the index score of r correlation, product moment r
xy
usually used the interpretation such as bellow.

xy
Interpretation
0.00—0.19 There is a relationship between X and Y, but the
correlation is very weak or little so it is ignored or it is considered no correlation in this rating.
0.20—0.39 There is a relationship between X and Y, but it is
weak or little. 0.40—0.59
There is a relationship between X and Y. The value is medium.
0.60—0.79 There is high relationship between X and Y.
0.80—1.00 There is a very high relationship between X and
Y.
G. Statistical Hypothesis
To know whether there is any significant correlation or not between X variable and Y variable, the statistical hypotheses were used as follows:
1. If r
o
r
t
= H
a
is accepted and H
o
is rejected. It means that there is a relationship between collocation knowledge and reading comprehension.
2. If r
o
r
t
= H
a
is rejected and H
o
is accepted. It means that there is a no relationship between collocation knowledge and reading comprehension.

CHAPTER IV RESEARCH FINDINGS AND DISCUSSION
A. Research Findings 1. Description of the Data
The research was conducted at Syarif Hidayatullah State Islamic University of Jakarta in which the fourth semester students of Department of English
Education were involved as the participants of the research. There were two different tests conducted in this study; collocation knowledge test and reading
comprehension test. The tests were conducted in order to get data of students’ collocation knowledge and their reading comprehension. The data was described
as follows:
a. Collocation Knowledge Score
These are the score of collocation knowledge gotten from the collocation knowledge test conducted by the researcher.
