Fifth, after the treatment that consisted of several meetings finish, then the writer administered post-test to students in the two classes the experimental class
and the controlled class by using the same format of pre-test. Finally the data that have been collected from the pre-test and post-test
were calculated using statistical calculation of t-test to figure out the result or conclusion of the research.

CHAPTER IV RESEARCH FINDINGS
A. The Description of Data
As the writer mentioned before, she took the experiments. She got the data from the pretest and the posttest of teaching narrative texts in two different
treatments within two different classes. In this part, the writer reported concerning the data description according to the pretest and the posttest from experimental
and controlled class as follows:

B. The Analysis of Data
In this research, the technique of data analysis is statistic calculation of „t‟
test, with significance 5 and 1 to decide significance of the difference result of teaching reading of narrative text by using group work and GTM experimental
class and controlled class.
