3.6 Method of the Data Analysis
This subchapter discusses normality test and t test. Each of this discussion is presented as follows:
3.6.1 Normality Test
I used parametrical statistic. I used parametrical statististic because the data were rasio. Parametrical test was considered to be the most powerful test.
Parametrical test required assumtion test. The one of the assumtion test is normality test.
The formula to analyze the normality test was:
If c

c

table the data is normal, but if c

c
2
table, the data is not normal.
3.6.2 T- test
The obtained data were analyzed to get the result. The matched T- test formula was used to analyze the data in this research. It was used to know that the
differences between pre test and posttest were significant or not.

CHAPTER IV RESEARCH FINDINGS AND DISCUSSION
Chapter IV presents the analysis and the discussion of the research findings. The chapter consists of analysis of each meeting, statistical analysis, and
discussion.
4.1 Analysis of Each Meeting
In this section, I discussed and analyzed the process of the study from the try out until posttest.
4.1.1 Try Out
Try out test was necessary since the result will be used to make sure that measuring instrument has such characteristic as validity and reliability. I made
two instruments test; they were for pre test and posttest. The test instrument A was for pre-test and the test instrument B was for posttest. I made different test
instruments for pre test and pos test. I made the test instruments based on bloom taxonomy. The steps of bloom taxonomy were remember knowledge,
understand comprehension, apply, analyze, evaluate and synthesis. I made the posttest instruments more difficult than those of the pre test. I made the pre test
based on three steps of bloom taxonomy. They were remembering knowledge, understanding comprehension, and applying. I made the posttest instrument
