F. Technique of Data collection
In this study, the writer used the quantitative research. Teams Games Tournaments TGT used in teaching narrative text to get the data. There were
tests as the main instrument that used in this study to see the effectiveness of Teams Games Tournaments TGT in teaching narrative text. To collect the data
the writer applied the steps as follows:
1. Pre-test
Pre-test was given to five classes 8D, 8E, 8F, 8G and 8H before the writer decided the experimental class and controlled class and gave the treatment
of Teams Games Tournaments TGT in teaching narrative text in the experimental class.
2. Post-test
Post-test was the last test that given to the both classes 8E and 8H after giving the treatment of Teams Games Tournaments TGT in the
experimental class. The aim of the giving post-test was to know the effectiveness of Teams Games Tournaments TGT in teaching narrative
text. Through implementing the pre-test and post-test, it can be seen the
progress of the students and the effectiveness of using Teams Games Tournaments TGT in teaching narrative text.
G. Technique of Data Analysis
The writer analyzes the data which taken from both classes 8E and 8H. Analyzing the data was the last step of the research to get the result of the
research. In this research the writer used T-test formula as a technique of data analysis. T-test was used to know the effectiveness of using Teams Games
Tournaments TGT and to know the difference of students’ score in both
experimental class and controlled class. Here is the form of the T-test:
= Mean of Variable X = Mean of Variable Y
SE = Standard Error
X = Experimental Class
Y = Controlled Class
N = Students
= t observation
Prior the calculation of the T-test there are several steps to be taken, they are as follow:
a. Determining the Mean of Variable X, with formula:
b. Determining the Mean of Variable Y, with formula:
c. Determining the Standard Deviation Score of Variable X, with formula:
d. Determining the Standard Deviation Score of Variable Y, with formula:
e. Determining the Standard Error Mean of Variable X, with formula:
