Hypothesis Testing
This research was conducted to answer the question whether Two Stay Two Stray TSTS Technique
has any effect on students’ ability in reading recount text on second grade students of SMP Dharma Karya UT. In order to provide an
answer for the question above, the Alternative Hypothesis Ha and Null Hypothesis Ho were proposed as follows:
a. Ho Null Hypothesis: Two Stay Two Stray TSTS Technique has no
significant effectiveness in learning reading of recount text. b.
Ha Alternative Hypothesis: Two Stay Two Stray TSTS Technique has significant effectiveness in learning reading of recount text
To prove the hypothesis, the obtained data from experiment class and control class were calculated by using t
test
formula with assumption as follows: a. If t0 ≤ t
table
, in significant degree of 1, the Null Hypothesis Ho is accepted and the Hypothesis Alternative Ha is rejected. It means that there is no
significant effect of Two Stay Two Stray TSTS Technique on students’ reading
recount text ability. b. If t0 ≥ t
table
, in significant degree of 1, the Null Hypothesis Ho is rejected and the Hypothesis Alternative Ha is accepted. It means that there is a
