CHAPTER IV THE RES ULT OF THE S TUDY
This chapter presents the result of the study. It is divided into four parts, namely: the description of the data, normality and homogeneity test, hypothesis
test, and the discussion of the result of the study.
A. Description of the Data
The data described are the result of the reading test. It includes the mean, mode, median, 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, namely:
1. The data of the reading test of the students or the group having high self- esteem who are taught by using Teams-Games-Tournament A

2. The data of the reading test of the students or the group having low self- esteem who are taught by using Teams-Games-Tournament A
