Data From Test Techniques of Data Analysis

CHAPTER IV RESEARCH FINDINGS AND DISCUSSIONS

This chapter presents and discusses the findings of the research based on the data obtained during the research. In line with the research problems, it consists the research findings as follows: 1 Data students’ improvement using TPR method in their vocabulary mastery in the classroom.2 affect using Total Physical Respond Method of the students’ ability in learning the vocabulary.

A. The Description of Data Students’ Improvement Using TPR Method in

Their Vocabulary Mastery in the Classroom In analyzing the data about the students’ achievement in learning vocabulary using TPR method which gained from experiment class or using GTM in the classroom is gained from controlled class, first the writer presents the result pre-test and post-test both of the class and its differences. Then the writer used the formula statistic calculation of t-test with significance 5 and 1 to decide significance of the difference result in teaching the vocabulary using TPR method in the instructional activities in the classroom and using GTM in the classroom at seventh grade students of MTs Khazanah Kebajikan. The following table, the writer presented the result calculation of test and its differences to know the effectiveness of using TPR method in the instructional activities of vocabulary in the classroom.

Table 4.2 shows the data about frequency of test result after learning the vocabulary by using TPR method in instructional activities in the classroom Table 4.2 The Result Calculation of Students’ Score of Experiment Class Score Frequency f X 1 � 1 � 1 2 7 – 12 4 1 27.5 3 12 144 13 – 18 7 2 14 196 19 – 24 3 1 3 9 25 – 30 9 31 – 36 4 -1 -4 16 37 – 42 2 -2 -4 16 43 - 48 1 -3 -3 9 Total 30 18 390 Base on the data presented in the table 4.2, above, it can be determined mean of variable x. standard deviation score of variable x. and standard error mean of variable x of the experiment class. the formulation as follow: a. Determining mean of variables x experiment class M 1 = M 1 + i ∑� 1 = 27.5 + 6

Determining of standard error mean of variable x experiment class SE M1 = � 1 1 −1 = 21.36 30−1 = 21.36 5.386 = 3.97 From the calculation above, the mean variable of the experiment class was 31.10, the standard deviation of the experimental class was 21.36, and standard error means of variable experiment class was 3.97 Then the table 4.3 showed below is the students’ score of controlled class which are obtained from the teaching vocabulary using GTM in the classroom, and for more detail information will be presented in the table below:
