CHAPTER IV RESEARCH FINDINGS
A. Data Description
The result of this research was acquired from a writing test. The writing test was divided into pre-test and post-test. Pre-test was given in the first meeting
and post test was given in the last meeting into both classes VIII-B as an experimental class and VIII-A as a controlled class. The data of each class will
be explained below.
1. The Data of Experimental Class
The following table is the score of pre-test and post-test in the experimental class VIII-B.

Based on the table 4.1 above, it can be seen that the lowest pre-test score is 44 and the highest score is 70 with the mean 60.46. Besides, the lowest post-test
score is 66 and the highest score is 85 with the mean 76.91. The students’ writing skill of recount text in the experimental class increase from the mean 60.46 on
the pre-test to 76.91 on the post test. It is proved from the gained score mean is 16.46. It can be concluded that there was a signifficant difference between
students’ achievement of pre-test and post-test. To see in detail result of pre-test
and post test in the experimental class, the writer used SPSS v.22 with steps as follows: open SPSS program → click variable view → input the information of
data data name → input the pre-testpost-test scores in data view → click
Analyze → Descriptive Statistics → Frequencies → put ‘pre-testpost-test score’
as the variable → click statistics → checklist mean, median, mode, sum,
minimum, and maximum → click continue → click charts → checklist histogram
→ click continue → click OK.

The table 4.2 above shows that the experimental class, VIII-B, consisted of 35 students. The mean score, the total of the data which is divided with the
number of data, is 60.46. Median score which is defined as the middle score of a number score arranged from lowest to highest score is 61. Besides, the mode
score is 59. It is the score that appears most often in a set of scores. In addition, the score has the lowest and highest score. The lowest score is 44 and the highest
score is 70. The sum score or the total score which is gained is 2116.
Based on the table above, it could be made a table of frequency distribution as follows:

To provide additional description of the data distribution of pre-test in the experimental class, the histogram of frequency distribution is presented in figure
