This can be seen in the descriptive statistics table as follows: RESEARCH METHOD This research was be conducted using a quasi experimental method. e research design used is the non randomize control group Pretest and Posttest Design. The experimental class and the control class are the two classes involved in this design. Before receivin g treatment to the two classes, they were given a pretest first, namely to find out the students' initial abilities (Mujahidin. Furthermore.

Referring to the explanation explained in the previous chapter, it is known that if the sig value> 0. 05 then the data is normally distributed. In the table there are experimental and control For data collection in this study the writer conducted pre-test and post test in both classes. So that the results of the normality calculation in the table above explain that for the experimental class the sig value in the pre-test is 0. > 0. 05 so that it is normally distributed. Likewise, the post-test sig value is 0. > 0. 05 so the data is normally Then for normality in the control class based on the table above, it is explained that the sig value in the pretest is 0. 040> 0. 05 so that the data is normally distributed. Likewise, the sig value in the post-test is 0. 075> 0. 05 so that it is normally distributed. So, in this calculation it can be concluded that the data is normally distributed. Based on the table above, it is known that sig = 0. 109> 0. 05, this shows that the variant data of the writing score in the experimental class is homogeneous.
