3. T-test of the data The writer conducted T-test formula to prove the hypothesis. This
is the last test that was purposed to find out the different of significant degree between increasing of pre-test and post-test result and the
achievement in both experimental and class controlled class. The writer has sought the formula as follows:
7
M І = Mean of experimental group Variable X
M Ї = Mean of controlled group Variable Y
SEM І = Standard error of mean Variable X
SEM Ї = Standard error of mean Variable Y
Afterwards, the calculation goes to several processes as follows:

1. Determining Mean of Variable X
2. Determining Mean of Variable Y
3. Determining Standard of Deviation Score of Variable X

CHAPTER IV RESEACH FINDING
A. Data Description
After presenting the material, the writer collected the data from both experimental class and controlled class. The data that he got were from
pre-test and post-test which gave to students of MTs Masyariqul Anwar. The test used was objective test or multiple choice form of the
experimental class and controlled class. The test consisted of 20 test items and the accumulation of the correct items was multiplied by 5. So, if the
students got 20 correct answer, they got 100 points.
1. The Data of Experimental class
In the following table is the score of pre-test and post-test in experimental class.

Based on the table 4.1 above, the result of the pre-test and post-test of the experimental class showed that the highest score on
pre-test was 85 and the lowest was 50 with average was 66.6. Thus, the researcher gave the treatment to the students of
experimental class by using realia to teach concrete noun. Then the result showed there a significant differences, the highest score
on post-test was 90 and the lowest was 60 with average was 76.3.
