CHAPTER IV RESEARCH FINDING
This chapter describes research finding which consist of the description of data, the analysis of data, the test of hypothesis and the interpretation of data.
A. Description of Data
1. The result of experimental and controlled class pre-test
The writer obtained data pre-test from experimental and controlled class by bar chart which consists of 30 students of the third grade after
conducting study

Diagram 4.1 Pre-test experimental and controlled classes
From the data above, the number of interval class and the length interval were 6 classes. The
table showed that students’ score in experimental class of pre-test and controlled class. The lowest score from

experimental class of pre-test was in class interval 52-58 with 8 students, and the highest score was 88-94 with 2 students. In addition, the lowest
class for controlled class was in interval 52-58 with 3 students, and the highest score was 88-94 only one student. For the calculating of statistical
description, it can be seen in appendix.
2. The Frequency distribution of Experimental and Controlled class
Pre-test
The test were presented in frequency distribution of experimental and controlled class pre-test table which consist of maximum score,
minimum score, mean, variance and standard deviation from the table below

3. The result of experimental and controlled class post-test
The writer obtained data post-test from experimental and controlled class which consist of 30 students of the third grade after
conducting study

Diagram 4.2 Post-test experimental and controlled classes
According explanation above there was 6 numbers of class intervals. On the other hand, the length of the class interval was 7 both of
class. The table from post test of experimental showed that the lowest score was in class interval 56-63 only one student and the highest score
was 92-98 with 3 students. Hence, the lowest class for controlled class was in interval 56-63 with 7 students, and the highest score was 92-98 no one
student. For the calculating of statistical description, it can be seen in appendix
