Table 4.2 shows the students’ initial names in controlled class, their pretest scores, their posttest scores and their gained scores. Based on the result of pretest
in controlled class, it can be showed the highest score and the lowest score of 38 students in the controlled class. In pretest, the highest score was 76 obtained only
by one student and the lowest score was 36. The mean score of pretest was 52.74. It was higher than the experimental class.
In posttest, it can be seen that the mean score of posttest was improved and it was 60.95 and the mean gained score was 8.21. Those are lower than posttest
mean score in experimental class. Meanwhile, the highest score of posttest was 88 obtained only by one student and the lowest score in posttest was 40 obtained by
one student too. Moreover, there were six students who had the higher pretest scores rather than their posttest scores. It can be concluded that there was still
improvement of the students’ achievement in learning narrative text although they were not taught by using DR-TA strategy.
B. Data Analysis
1. Result of Pretest of Experimental and Controlled Class
The result of pretest of experimental and controlled class based on SPSS version 22 was gained from the steps as follows: Analyze
→ Descriptive Statistics → Frequencies. Insert Experimental X in variable → Click Statistics and
Checklist Mean, Median, Mode, Sum, Std. deviation, Variance, Minimum and Maximum → Continue → OK. Result gained from the pretest in class X.5 as the
experimental class of the research is presented in Table 4.3 below:

Table 4.3 shows that the data of the experimental class is 38 students. The total of all data which are divided into the number of data determined as mean
score from the experimental class is 51.74. Median score is 54.00. The median is the numerical value separating the higher half of a data sample, a population, or a
probability distribution, from the lower half. The mode is defined as the element that appears most frequently in a given set of elements and the mode score of the
experimental class is 40. The set of scores constitute a population determined as variance score which is 171.280 and 13.087 for standard deviation. Standard
deviation is a quantity calculated to indicate the extent of deviation for a group as a whole. The highest score of the experimental class is 76 and the lowest score is
24. The summation of the pretest score in experimental class is 1966.
From the Table 4.3, it can be made a table of frequency distribution which is presented as follows:

Table 4.4 is a tool of presentation consisting of columns and rows and there are numbers which describe the division and the percentage of frequency
distribution.
Beside the table of frequency distribution, it also can be described by a diagram which is presented as follows:

In analyzing the result of pretest has the same steps except the inserted variable is not the experimental X but the controlled Y. Result gained from the
pretest in class X.6 as the controlled class of the research is presented in Table 4.5 below:
