43 Afterwards, the researcher analyzed the degrees of the students’ ability by using
SPSS v.16. The details are presented in the table.

The table 4.3 presents that there were 2 students 3.3 at the low score on writing an argumentative essay. Then, there were 6 students and 6 students 10;
10 got the moderate nearly score on writing an argumentative essay. The table showed that there were 10 students 16.7 at the moderate up to high score.
Then, the table also showed that there were 2 students 3.3 at the high score on writing an argumentative essay. By using the software of SPSS v.16, the
researcher had calculated that the mode was 84 and the mean was 79.97; while the median was 81.50. It showed that most of the students had good ability on writing
an argumentative essay. The distribution of the data was evenly spread. By PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
44 calculating the variance of the data, the standard deviation of this variable was
7.378. Therefore, the researcher would like to present the graphic in order to show the significant of the
students’ argumentative essay scores and the frequency.

Graphic 4.2 provides the frequency of the students’ argumentative essay
scores in the variant group. Most of the students were moderate up to high scores. It meant that CRW II class had provided an opportunity for the students to
enhance their ability on writing an argumentative essay.
4.1.4. The Raw Data of the Questionnaires
The questionnaires were made by combining with some questions, which could investigate the possibility of the relationship between the self-management
45 ability and students’ ability on writing an argumentative essay in CRW II class.
The questionnaires considered as questionable because it presented the degrees of self-management ability mostly. The researcher used the checklist and rating scale
likert scale in order to find out the degrees of self-management ability in enhancing the students’ ability on writing an argumentative essay. The researcher
used 3 in rating scale to make the participants acquitted in answering the questionnaires. Cohen et al. stated that using 3 in rating scale might prevent the
lack of open-ended questionnaires which the participants were unwilling to answer definitely for one reason or another Cohen, Manion, and Morisson, 2007,
p. 158. After collecting the questionnaires, the data were categorized into some groups in order to find out the frequency and the percentage of the data. The
checklist and rating scale were presented as the following:

The questions in these questionnaires were intended to answer the research problem or provide the data needed by the researcher.
4.1.5. The Correlation between the Self-Management Ability and Students’
Ability on Writing an Argumentative Essay in CRW II Class
After analyzing the data from the degrees of self-management ability and the students’ ability, the researcher found a positive correlation. The result of the
finding in this research was shown in the graphic 4.3. Graphic 4.3 visualizes the relationship between the degrees of self-
management ability and the students’ ability in CRW II Class which was analyzed by using the students’ argumentative essay scores. The dots were plotted within
the graph presenting the positive relationship between these two variables. The researcher calculated and found that there was a significant correlation between
the self- management ability and students’ ability on writing an argumentative
essay. These strong positive correlation coefficients would be presented in this research.
