CHAPTER IV THE RESULT OF THE STUDY
This chapter discusses the result of the study. The result is divided into four discussions as follows: the description of the data, normality and
homogeneity test, hypothesis test, and the discussion of the result of the study.
A. The Description of the Data
The data presented are result of the reading test. It includes the mean, mode, median, standard deviation, and frequency distribution then followed by
histogram and polygon. The descriptions of data are based on the groups analyzed which are divided into eighth groups:
