multiple choices. There are 40 forty items in the test and the whole are multiple choices. If students answered a question correctly, they
would be given score 2.5 for complete sentences. So the score of students for the whole, if they answered are 100.
G. Technique of Analyzing the Data
Analyzing the Data is the last step in the procedure of experiment, in this case, processing the data. Data processing is the step to know the result
of both the experiment class and control class and also their differences. In analyzing the Data, the writer compares the score between pre-test
and post-test of bot the experiment class and control class to find out the differences score of student’s achievement in teaching imperative sentences
by using TPR. This research was analyzed by using T-test.

H. The Testing of Hypothesis
The statistic hypothesis stated:
Ha : Using total physical response method is effective toward the
students’ imperative senteces mastery.
Ho : Using total phyisal response is not effective toward the
students’ imperative sentences mastery. According to the statistiacl hypothesis, H
a
accepted if the average score of calculation t

t-observation is smaller than t

CHAPTER IV RESEARCH FINDING AND INTERPRETATION
A. Data Description
The writer collected the data from students pre-test and students post-test from both of classes. The data described into two tables. The students’ score
imperative sentences mastery presented in table 4.1 and the students’ score
imperative sentences mastery presented in table 4.2. The pre-test same as with post-test consist of 40 forty items in the test.
It’s all question are multiple choice, if students answered a question correctly, they would given 2.5 for multiple choice. Then the scores for the whole of items
are 100. To know the scores of the test, it was presented in table below.
