2. Result of Linearity Test
Before analyzing the data by using Pearson product moment formula, the first checked out whether the data obtained were linear or not because this was one of
requirements to be able to used the Pearson product moment formula such in the explanation in chapter three. SPSS used to check it in order to make the researcher
easy because this program could make a clear graph of linearity. Based on the table, the data were linear see Appendix 22 for the significant level was lower than
significant level α 0.00 0.05.
3. The Result of Hypothetical Test
The hypothesis is very important to find out whether or not the alternative hypothesis H
a
or null hypothesis H
o
is accepted in this research. The Rank Spearmans’
formula by using SPSS Statistical Package for the Social Sciences was computed for testing hypothesis. In this case, the criteria of hypothesis test as follows:
The hypothesis formulas were: H
�
∶ There was significant Correlation Between Students’ Simple Present Tense Mastery and their Ability in Writing Descriptive Text at the First Semester of
the Eighth Grade of SMPN 1 Karya Penggawa Pesisir Barat in 20162017 Academic Year.
H
O
: There was no significant Correlation Between Students’ Simple Present Tense Mastery and their Ability in Writing Descriptive Text at the First Semester of
the Eighth Grade of SMPN 1 Karya Penggawa Pesisir Barat in 20162017 Academic Year.
While the criteria acceptance or rejection of hypothesis tests are: H
o
was accepted if Sig. α = 0.05
H
a
was accepted if sig. α = 0.05

Writing Descriptive Text at the First Semester og the Eighth Grade of SMPN 1 Karya Penggawa Pesisir Barat in 20162017 Academic Year.
C. Discussion
Based on the result of research, it had shown that simple present tense mastery positively correlated with
students’ ability in writing descriptive text. Based on the result above, it can be seen that the result was higher. Besides that, simple present
tense mastery can improve each aspects of students’ ability in writing descriptive text.
At the beginning of activity, the try out was conducted in SMPN 1 Karya Penggawa Pesisir Barat on October 7
th
, 2016. Try out test was given to 30 students of the eighth grade out of the sample. The writer prepared 50 items of multiple choice questions for
simple present tense mastery. And three pictures for writing descriptive text test. It has purpose to know how accurate and effective the test before they were used to
collect the data of research and identify whether the test can be given or not. Then, the test items were evaluated to get good items that were tested in the test. It can be
seen from the result of validity and reliability of the tests. After knowing the result of validity and reliability test from try out, it can be seen that the result of try out based
on anates and inter rater showed that the instrument was valid and reliable.
The number of the result of items validity for simple present tense mastery test that was valid 40 items from 50 items. The result of validity test for writing descriptive
text test showed the items were valid. In this research, the writer used picture as
