This chapter shows the result of study. It consists of four parts, the description of study, normality and homogeneity test, data analysis, and the
discussion of the result of the study.
A. Description of Study
There are 2 classes of Reading 3 used for the research, class I and class III. For the sake of research, students who join in class III are taught by using
reciprocal teaching while students who sit in class I are taught by using direct instructional model. Each class consists of 40 students. There is a border
separating the students. The border is their level of intelligence. The data described here are the result of the reading test. The description
includes 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, they are as follows: 1. The data of the reading test of the students or the group having high intelligence
who are taught by reciprocal teaching A

To describe the data, the writer works on the highest score, the lowest score, the range, the class, and the interval to know the frequency distribution. The
data of each group are presented as below: 1. The data of reading test of students having high intelligence who are taught by
using Reciprocal Teaching A

shows that the score is 70 up to 90. The mean is 79.6, the standard deviation is 6.16, the mode is 77.5, and the
median is 78.7. The frequency distribution of the data of A

is in table 3. The highest score is 90 while the lowest score is 70. From these, the range is 20. The
class is 4, and the interval of these scores is 6. Histogram and polygon are presented in figure 4.
