F. Technique of Data Analysis
The writer calculated the perquisite testing requirement analysis such as
validity, reliability, linearity, and normality test before calculating the statistical testing Pearson Product Moment Correlation.
a. The Validity Test
An instrument is valid when if it is able to measure what the researchers are going to measure.
3
There are two criteria to determine validity of test items, as
follows:
1. If r
value
r
table
at the level significance of 5, it means that the instrument is valid.
2. If r
value
r
table
at the level significance of 5, it means that the instrument is not valid.
The calculation of validity test used correlation formula from Statistical Package for Social Science SPSS version 21. The result of the validity test items
are consulted to r
table
for N = 40 at the level of significance of 5. The result showed that the coefficient validity of reading habit and reading comprehension
were valid. The result of validity test computation can be seen in the appendix.
b. The Reliability Test
Reliability test refers to consistency if the instrument used repeatedly for different subject or different time.
4
The instrument is reliable if:
1. If alpha cronbach r
table
at the level significance of 5, it means that the instrument is reliable.
2. If alpha cronbach r
table
at the level significance of 5, it means that the instrument is not reliable.
The following is the result of the reliability of reading habit X and reading comprehension Y test.

5 40 Description
X 0,801
0,312 Reliable
Y 0,733
0,312 Reliable
The computation showed that the coefficient reliability of reading habit was on 0,801 while the coefficient reliability of reading comprehension was on 0.733. It
could be concluded that all of these instruments were reliable and consistent. The computation result of reliability test can be seen in the appendix.
G. Statistical Hypothesis
Statistically, the formulation of hypothesis as follows:
Ha = Alternative hypothesis That means there is significant relationship
between students’ reading habit and their reading comprehension
Ha accepted if: r
o
r
t
α, n – 2 or t
o
t
t
α, n – 2. Ho = Null hypothesis
That means there is no significant relationship between students’
reading habit and their reading comprehension. Ho accepted if:
r
o
r
t
α, n – 2 or t
o
t
t
α, n – 2.
