it is concluded that t

is significant, there is a difference between experimental and control group.
3.14.2 Normality
In order to prove the pre test post test of each group to be normally distributed, it is used the normality methods. We can use the following formula:
If the value of x

α , the pre test post test for each group is said to be normally distributed.
3.14.3 Homogeneity
To find out homogeneity of data. The writer uses the “homogeneity formula” as follows:
In which : Vb

: variant of the pre test post test of controlled group If the F

CHAPTER IV RESEARCH RESULT AND DISCUSSION
This chapter presents the activities of experiment, result of try-out, pre-test, and post-test, significance difference between two means of pre-test and post-test, test
of significance, result of questionnaire, and discussion of the result. It deals with both writing achievement of the students who were given British Council
Animation as the media and who were given conventional technique. It also deals with the difference in writing achievement between the two groups of the
students.
4.1 Analysis of Each Meeting
In this section, will be discussed and analyzed the process of the experiment since the two groups were in the same level of writing comprehension.
4.1.1 Try Out
The students were given a try out before the pre test was conducted. Try out was given neither for group of experimental nor control group. It was done to class
VIII A of SMPN 2 Kendal. It was conducted on 30 April 2011. The test was a written test. The students have to write a narrative text based on the picture given.
The complete analysis of try-out can be seen in appendix 13. The following are the data interpretation of the try-out test
