CHAPTER IV RESEARCH FINDING AND INTERPRETATION

In this chapter, the writer analyzed and interpreted all data which were collected during the research. This chapter was divided into 4 subchapters: Data Description, Data Analysis, Hypothesis Testing, and Interpretation of data.

A. Data Description

In this chapter, the writer displayed the description of pre-test and post-test data. The data were collected from students’ pre-test and post-test in both two classes, experimental and controlled class. To find out the result of the test Pre-test and post-test the writer made the table of the students’ score as follow: Table 4.1 The Score of Pre-test and Post-test Experimental Class Students Pre-test Post-test Gained Score 1 30 66 36 2 56 76 20 3 56 66 10 4 46 50 4 5 50 76 26 6 56 80 24 7 60 70 10 8 56 86 30 9 56 50 -6 10 36 76 40 11 70 86 16 12 60 96 36 13 56 76 20 14 40 73 33 15 66 66 16 66 83 17 17 50 90 40 18 36 70 34 19 60 86 26 20 46 83 37 21 60 76 16 22 46 80 34 23 66 86 20 24 56 73 17 25 60 76 16 26 60 83 23 27 60 48 -12 28 60 90 30 29 56 76 20 30 66 86 20 Total 1642 2279 637 Mean 54.73

75.97 21.23

Based on the table 4.1, it showed that the mean of the pre-test in the experimental class was 54.73. In the other hand, the mean of the post-test was 75.97. The highest score in pre-test was 70 and the lowest score in pre-test was 30. While, the highest score in post-test was 96 and the lowest score in post-test was 48. It could be summarized that the highest and the lowest score in post- test was higher than in pre-test. It means that the stud ents’ vocabulary were increased. This is the histogram graph.
