G. Statistical Hypothesis
In order to get the answer of the hypothesis above, the researcher proposed alternative hypothesis H
1
and null hypothesis H which was provided as
follows: H
= sig. 2-tailed of t-test 0.05 H
1
= sig. 2-tailed of t-test 0.05 Where:
H : There is no effect of using Question Generation Strategy in learning
reading of narrative text. H
1
: There is an effect of using Question Generation Strategy in learning reading of narrative text.
If sig. 2-tailed of t-test 0.05, H null hypothesis is accepted, and H
1
alternative hypothesis is rejected. If sig. 2-tailed of t-test 0.05, H
null hypothesis is rejected, and H
1
alternative hypothesis is accepted.

CHAPTER IV RESULT AND INTERPRETATION
This chapter discusses about result and interpretation of the study. The chapter provides the description of the data, the analysis of the data, and the
interpretation of the data.
A. Result
1. The Description of the Data
After conducting the research at SMPN 1 Tambun Selatan, the writer got the data by taking students’ pre-test and post-test score on reading narrative text
test. The pre-test was given before the treatment and the post-test was given after the treatment.
In this research, the researcher gave treatments to both experimental class and control class about reading narrative text. In the experimental class the
researcher implemented Question Generation Strategy QGS, while in the control class the researcher implemented silent reading.
The Table 4.1 below showed the result of the test which was analyzed the students’ scores of pre-test and post-test in experimental class variable X.

Based on table 4.1 above, it could be seen some scores of pre-test and post-test of experimental from 40 students. The sum pre-test score of experimental
class was 2496 while the sum post-test score of experimental class was 3404. The mean pre-test score was 62.4 and the mean post-test score was 85.1. The lowest
score in the pre-test was 28 and the highest pre-test score was 88, while the lowest post-test score was 76 and the highest post-test score was 96.

Table 4.2 showed some scores in pre-test and post-test of control class from 40 students. The sum pre-test score of control class was 2548 while the sum
post-test score of control class was 3268. The mean pre-test score was 63.7 and the mean post-test score was 81.7. The lowest score in the pre-test was 48 and the
highest score was 80 and the lowest post-test score was 72 and the highest post- test score was 96.
1 Result of Pre-test of Experimental class and Control Class
The addition results from pre-test in class 8B as the experimental class of this research were presented in a table below:
Table 4.3 Table of Data Statistics of Pre-test Result of Experimental class
N Valid
40 Missing
Median 60.00
Mode 56
Std. Deviation 14.906
Variance 222.195
Range 60
From table 4.3 above, it showed that the total students of experimental class were 40 students, median score was 60.00. The median was the numerical
value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. Next, mode score which was defined as the
element that appears most frequently among the students’ score was 56. The set of
scores constitute a population determined as variance score was 222.195, and standard deviation was 14.906. Standard deviation was a quantity calculated to
indicate the extent of deviation for a group as a whole. The range score was 60.
