C. Result of The Research
1. Result of Pre-Test
At first meeting the researcher conducted pre-test in order to find out the previous students‟ analytical exposition text writing ability. The pre-test was administrated on
November 24
th
, 2016 at 10.00 a.m for the XI IPA 1 as the experimental class and at 1.00 p.m for class XI IPA 2 as the control class. The analysis showed that the mean
score of pre-test in control class was 58.3. The higher score was 70 and the lowest score was 51 see appendix 15. While in the experimental class the mean was 57.7.
The highest score was 68.5 and the lowest score was 48.5. see appendix 15
2. Result of Post-test
After conducting three meetings of treatments the researcher conducted the post-test to the sample. The researcher conucted post-
test to see whether the students‟ score increased or not. The post-test was conducted on December, 24
th
2016, 2016 at the 10.00 a.m for the XI IPA 1 as the experimental class and 1.00 p.m for the class XI
IPA 2 as the control class.
The analysis showed that the mean score of post-test in control class was 70.6. The highest score was 83.5 and the lowest score was 64.5 see appendix 15. While in
experimental class the mean score was 78.4. The highets score was 86 and the lowest score was 70.5. See appendix 15
From the mean score of both experimental class and control class, it can be attained that there was significant difference of students‟ writing achievement between the
class that was taught by using Dictogloss technique and the class that was taught through Free Writing technique. It can be seen from the table :
Table 5 Comparison result between Pre-Test and Post-Test
No Class
Pre-Test Post-Test
1 Control
58.3 70.6
2 Experimental
57.7 78.4
Having seen the table of comparison between pre test and post test, we could see the increasing of the students‟ score See appendix 15. From the table above, it could be
seen in the experimental class that Dictogloss tec hnique could increase the students‟
writing score of analytical exposition text from 57.7 to 78.4.
D. Result of Data Analysis
1. Fulfillment of the Assumptions
Parametric statistical significance tests, such as analysis of variance and least squares regression, were widely used by researcher in many discplines, including, statistics
parametric tests to produce accurate results, the assumptions underlying them such as normality test must be satisfied
a. Result of Normality Test
The normality test is used to measure weather the data in the experimental class and
the control class are normally distributed or not.
The hypotheses are : H
o
= the data have normal distribution H
a
= the data do not have normal distribution
The criteria of acceptance are : H
o
is accepted if L
observed
is lower than L
critical
, it means that the diistribution of the data is normal.
H
a
is rejected if L
observed
is higher than L
critical
, it means that the distribution of the data is not normal.

Based on table , it can be seen that in the experimental class and control class showed that L

L
critical.
The researcher concluded that the data in both classes were normality distributed See appendix 16-17.
