CHAPTER IV THE RESULT OF THE STUDY
This chapter discusses the result of the study. The result is divided into four di s cus s ions as fol l ows : the des cri pti on of t he dat a,
norm ali t y and homogeneity test, hypothesis test, and the discussion of the result of the study.
A. The Description of the Data
The data presented are
-
the 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 the data are based on the groups analyzed which are divided into six groups:
1. The data of reading test of the students or the group having high intelligence who are taught by using Three Phase Technique A
