CHAPTER IV RESEARCH FINDINGS AND DISCUSSION
A. Introduction
This chapter will present the result of the research and discuss the research findings. In other words, this chapter presents the answer of the research problems
as formulated in the first chapter. Firstly, this chapter presents the result of the tests; both the pre test and the post test as well as the analysis of the test, and
secondly it presents the result of the observation.
B. Presentation of the Tests Result
In order to find out the improvement of the students’ vocabulary mastery, there were two tests administered to gather the data. Both the experimental group
and the control group did the pre test. Pre test was conducted to see the input competence of both groups before treatment, whereas the post test was conducted
to see whether or not there was a significant progress after the treatment. This sub topic is divided into three parts and those are data presentation of the pre test, data
presentation of the post test and the descriptive statistics.

Table 4.1. The Pre Test Score of the Experimental Group and the Control Group
The table above shows that the mean scores of the experimental group and that of the control group are not far different. The mean score of the
experimental group is 3.92 and the mean score of the control group is 3.96 with 24 cases of each group. There were not any students of both groups who got the
maximum score 18. The maximum score of the experimental group was 9 and the minimum score of the group was 2. The Control group had the maximum score 8
and minimum score 2.
1.2. Data Presentation of the Post Test
The Post test was conducted after the treatment to both experimental and control groups. The table below shows the result of the post test of both
experimental group and control group.
