F. Statistical Hypotheses
Before deciding the result of the hypotheses, the writer proposed two
hypotheses to be tested:
a. H
o
: there is empirical evidence that the use of Two Stay Two Stray TSTS technique is not effective in teaching reading in second grade
SMP Dharma Karya UT.
b. H
a
: there is empirical evidence that the use of Two Stay Two Stray TSTS Technique is effective in teaching reading in second grade
SMP Dharma Karya UT. c.
H
o
: µ
1
= µ
2
d. H
a
: µ

≠ µ
2
And then, the criteria used as follows: a.
If ≤ t
table,
in significant degree of 5 and 1, the Null Hypothesis H
o
is accepted and Ha or Hypothesis Alternative is rejected. It means
that that there is not empirical evidence that the use of Two Stay Two Stray TSTS Technique is effective in teaching reading.
b. If
≥ t
table,
in significant degree of 5 and 1, the Null Hypothesis H
o
is rejected and Ha or Hypothesis Alternative is accepted. Therefore, there is empirical evidence that the use of Two Stay Two
Stray TSTS Technique is effective in teaching reading.

CHAPTER IV RESEARCH FINDINGS
This chapter contains the description of the data, the analysis of the data, and the discussion of the findings.
A. Description of the Data
This chapter describes general description of data gained by researcher during the research. The data were collected from the result of pre-test and post-
test from both experiment class and the control class. The data were depicted into two tables. The tab
le 4.1 showed the students’ score and achievement in control class and the table 4.2 showed the students’ score and achievement in experiment
class. During this research, the researcher extended the material to students
about recount text with reading as a focused skill. The treatment to experimental class and control class: Two Stay Two Stray TSTS Technique was implemented
in the experimental class. W hile in the control class, the writer didn’t use Two
Stay Two Stray TSTS Technique. After that, the writer measured studen ts’
reading ability by using a test in multiple choices forms. The validity and reliability instrument test was conducted before he
administered the test to both classes. There were 30 numbers of questions given to the 40 students of class VIII.1 SMP Yadika Pasar Minggu Jakarta Timur. From
the validity and reliability test, there were 25 valid questions from 30 questions which were gained. Further information about validity and reliability result can be
seen in the appendix.
