E. Technique of DataAnalyzing
Tests are used by the writer in collecting the data. The data from test are gained to find out the result of students’ reading comprehension achievement by
using CIRC technique. After getting the data, the writer used t-test, which was adapted by Anas
Sudiyono, to find out the effect of using CIRC technique to improve students’
reading comprehension. The writer has to seek the significant differences result of two samples
between pre-test and post-test by using formula as followed:
1
The writer has to seek score of t test as followed: 1. Seek D Diference between score of variable I X and score of variable
II Y and then D=X-Y 2.
Add D then getting ∑D 3. Seek Mean from Difference by using formula:
4. Seek the standard of Deviation from Difference SD
D
by using formula:
√
5. Seek the standard error from Mean of Difference by using formula:
=
√
1

6. Seek t by using formula:
After the data was calculated, the last procedure is determining df degree of freedom with formula:
Df =N – 1
Where: M
D
=Mean from differences SD = Standard of deviation
SE =Standard error N = Number of students
Df = Degree of freedom
F. Statistical Hypothesis
The statistical hypothesis of this research can be seen as: H
: There is no significant difference achievement of recount text between before and after implementing CIRC technique
H
a
: There is significant difference achievement of recount text between before and after implementing CIRC technique
Furthermore the writer has the criteria used as follows: 1. If t-test t
t-table t
t
in significant of 1 and 5, H the null
hypothesis is rejected and H
a
is accepted. It means that the rates of mean score of post-test is higher than pre-test. The using of CIRC
technique is effective to improve students’ reading comprehension.
2. If t-test t t-table t
t
in significant of 1 and 5, H the null
hypothesis is accepted and H
a
is rejected. It means that the rates of mean score of post-test is same as or lower than pre-test. The using of
CIRC technique is not effective to improve students’ reading
comprehension.
