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 2 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 1 B 1 6. The data of the reading test of the students or the group having low intelligence quotient that are taught using Contextual Teaching and Learning Method A 1 B 2 commit to user 72 7. The data of the reading test of the students or the group having high intelligence quotient that are taught using Grammar Translation Method A 2 B 1 8. The data of the reading test of the students or the group having low intelligence quotient that are taught using Grammar Translation Method A 2 B 2 . The data of each group are presented as below: 1. The data of the reading test of the students or the groups that are taught using Contextual Teaching and Learning Method A 1 Descriptive analysis of the data of A 1 shows that the score is 40 up to 83. The mean is 63.1 the standard deviation is 12.0, the mode is 59.1, the median is 63.5. The frequency distribution of the data of B 1 is in table 6, histogram and polygon are presented in figure 3.
