1
M : Mean of the score of control class
Σ
y
: Sum of the students’ score of control class
N : Number of the students of control class
SEMx : Standard error of experimental class SDx
: Standart deviation score of experimental class
SDy : Standard deviation score of control class
6. Determining standard errors of mean of variable Y, with the formula as follows:
SE =
SD N
1
7. Determining of standard errors of different mean variable X and variable Y, with the formula as follows:

SEᴍ ² + SEᴍ ²
8. Determining to, with the formula as follows:
t = M
M SEᴍ
SEᴍ
9. Determining t-table with the degree of freedom df in significant level 5 and 1 with the formula as follows:
Df = N + N 2
SEMy : Standard error of control class
Mx : Mean of the score of experimental class
My : Mean of the score of control class
SEMx : Standard error of experimental class SEMy : Standard error of control class
Df : Degree of freedom
N : Number of students of experimental class
N : Number of students of control class
H. The Statistical Hypothesis
The hypothesis of statistic that used in this research is: H
0 : μ 1 = μ 2 Ha : μ 1
μ 2
H0 : Null Hypothesis Ha : Alternative Hypothesis
μ 1
:
The students’ achievement in writing recount text, who are taught by using
storytelling technique.
μ 2
:
The students’ achievement in writing recount text, who are taught without
using storytelling technique.
The assumption of the hypothesis as follows: 1.
If t-test t-table in significant level of 5, the null hypothesis is rejected and the alternative hypothesis is accepted. It means that there is significant
difference between the students
’
speaking achievement by using storytelling technique
and the students’
speaking achievement without using storytelling technique at the eleventh grade students of MAN 1 Bekasi 1
2 . The use
of storytelling technique is effective to enhance students’ s
peaking skill. 2.
If t-test t-table in significant level of 5, the null hypothesis is accepted and the alternative hypothesis is rejected. It means that there is no significant
difference
between the students’
speaking achievement by using storytelling technique
and the students’
speaking achievement without using storytelling technique at the eleventh grade students of MAN 1 Bekasi 1 = 2. The use
of storytelling technique is not effective to enhance students’ speaking skill.

CHAPTER IV RESEARCH FINDINGS
A. Data Description
The part shows the general description of the students’ scores in both the
experimental class and control group. The description is divided into some sections: pre-test, post-test, gained score, and data analysis.
And it is the data were collected from the results of students’ scores of pre
-test and post-test in both experimental class and control group. The followings are the
descriptions:
