CHAPTER IV DATA ANALYSIS AND RESULT OF THE STUDY
In connection with the data analysis, I applied both non-statistical and statistical analysis to make the results of the students’ achievement interpretable
and readable.
4.1 Non-Statistically Analysis.
4.1.1 Test Result
The students’ problem in writing composition was divided into five
components. They were fluency, grammar, vocabulary, content and spelling.
Fluency : measuring the students’ ability of using the style or kinds
of sentences in their composition. Grammar
: measuring the students’ ability of using grammar such as articles, preposition and etc.
Vocabulary : measuring the students’ ability of choosing the appropriate words.
Content : measuring the students’ ability of using sentences
according to the topic. Spelling
: measuring the students’ ability of writing words correctly in their composition.
Based on the analysis of the students’ results of the composition which was scored using Heaton’s grid, each percentage of the total of the five
46
components was 19.93, 18.85, 20.30, 21.02, 19.88 for the Experimental Group and 20.11, 18.91, 19.85, 20.89, 20.21 for the
control group.
4.1.2. Test Scoring
After administering the test, I got the result of the students’ achievement as shown in appendix.
In order to further know the students’ achievement in detail; I used the following formula to find out the achievement of each component. The formula:
Table 3 Formula for calculating the achievement of each component
Ssa= 100
. X
Ss Stsc

∑
Where : Ssa = Students’ achievement
OSc Σ
= number of obtained scores Stsc = Sub total score
Ss Σ = Number of students
For Experimental Group, the computation is a.

From the result shows that the component of content of the Experimental Group got the highest percentage of the achievement, 89.17. This phenomenon
occurred due to the using of pictures as media so the students easily compose their descriptive paragraph.
