CHAPTER IV THE RESULT OF THE STUDY
This chapter presents the result of the study. It is divided into four parts, the description of data, normality and homogeneity test, hypothesis test, and the
discussion of the result of the study.
A. The Description of the Data
The data described here are the result of the reading test. The description includes the mean, the mode, the median, the standard deviation and
frequency distribution followed by histogram and polygon. Based on the group analyzed, the descriptions of the data are divided into eight groups as
follows: 1. The data of the reading test of the students or the group that are taught
using Contextual Teaching and Learning A
1
2. The data of the reading test of the students or the group that are taught using Grammar Translation Method A
2
3. The data of the reading test of the students having high intelligence B
1
4. The data of the reading test of the students having low intelligence B

5. The data of the reading test of the students or the group having high intelligence quotient that are taught using Contextual Teaching and
Learning Method A
