From the table above, it can be seen that the value of cronbach’s alpha is 0.813. That meant that the questionnaire was
reliable because the score was bigger than 0.60.
2. Test
The test instrument played an important role in collecting the data. In this research, the researcher administered test to the students to
know students’ reading comprehension score. The reading material and its question were selected from students’ book and other sources
wich was suitable with their level. The researcher used multiple choice types in order to make the score more objective. Here was the indicator
of descriptive reading comprehension test. In addition, the researcher clasified
the students’ score of reading comprehension into some measurable categories as follows :

The score of students
Category 80
– 100 High
70 – 79
Medium – 69
Below minimum competence criteria
KKM
Based on the try out result of the test validity of the 35 items, it showed that 22 items were valid. The number of invalid items were 3,
4, 6, 7, 11, 12, 14, 20, 22, 23, 24, 25, 34.
Table 3.7 Cronbach Alfa Table
From the table above, it can be seen that the value of cronbach’s alpha is that 0.726. That meant that the test was reliable because the
score was bigger than 0.60.

E. The Technique of Data Analysis
After getting the questionnaire data from the students, the researcher had to analyze the data and correlate the questionnaire score
and reading comprehension test.
To analyze the data, the writer used Pearson Product-Moment Correlation Coefficient.

√ Note :
r = Coefficient of correlation between X variable and Y variable
N = Number of respondent
=
The sum of the product of X and Y scores for each students = The sum of X scores
= The sum of Y scores = The sum of quadrate of each X scores
= The sum of quadrate of each Y scores = The sum of quadrate of each
scores = The sum of quadrate of each
scores
Before testing the t
count
the researcher made two hypotheses of signicance, they are:
Ha : there is a significant correlation between two varibales Ho : there is no significant correlation between two varibales
The formulation of test : a. If t

, it means that the null hypothesis is rejected and there is a significant correlation.
b. If t

, it means that the null hypothesis is accepted and there is no significant correlation.
