CHAPTER IV RESEARCH FINDING AND DISCUSSION
This chapter describes the research finding and the discussion. It concerns the description of the data pre-test and post-test, the analysis of the data, the testing
of the hypothesis, and the interpretation of the data.
A. The Description of the Data
The writer collects the data from students’ pre-test and post-test score of experimental class. The pre-test is given before the treatment begins and the
post-test is given after the treatment finish. Table 4.1 presents the students’ achievements in the experimental class before the writer does his experiment
pre-test. In addition, table 4.2 presents the students’ achievements after the writer does his experiment post-test in the experimental class.
