significant level α = 0.05. If the result was lower than α, it means that the data were linear.
c. 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. Non parametric statistics, rank spearman’s formula was used for hypothesis test. Rank spearman’s formula is
used to find the relationship between two variables, but there are unmet requirements for using pearson’s correlation. The requirements include the data was not of value,
or the data not have a normal distribution.

It means that rank spearman’s formula is an alternative from paramentric test bivariate correlation pearson’s correlation to
find the relationship between two variables that not have normal distribution. In this research, rank sp
earman’s formula was used for the hypothesis test because a result of one of the data that is present tense mastery test did not have a normal distribution. It
can be seen appendix 22. In this case, statistical computation by using SPSS Statistical Package for Social
Science of version 16 was used for hypothetical test. The purpose of using SPSS of version 16 in this case was for practicality and efficiency in the study. While the
criteria acceptance or rejection of normality test are: H
a
is accepted if sig α = 0.05
H
o
is accepted if sig α = 0.05

The hypotheses are: H
a
= There is a correlation between students’ simple present tense mastery and their
ability in writing descriptive text at the first semester of the eighth grade at SMPN 1 Karya Penggawa Pesisir Barat in 20162017 Academic Year.
H
o
= There is no correlation between students’ simple present tense mastery and
their ability in writing descriptive text at the first semester of the eighth grade at SMPN 1 Karya Penggawa Pesisir Barat in 20162017 Academic Year.
CHAPTER IV RESULT AND DISCUSSION
A. Findings
1. Data Analysis
To analyze the data, SPSS Statistical Package for the Social Sciences version 16 is used to get the result of the simple present tense mastery, result of the ability in
writing descriptive text, result of the normality test, and result of the linearity test. In this case, non parametric statistics,
rank spearman’s formula by using SPSS Statistical Package for the Social Sciences version 16 was used to getting the result
of the hypothesis testing. It used rank spearman’s formula because a result of one of
the data that is simple present tense mastery test did not have a normal distribution.
2. Result of the Tests
a. Result of the Simple Present Tense Mastery
The test was conducted in order to see students’ ability in simple present tense
mastery. The test was administered in SMPN 1 Karya Penggawa Pesisir Barat on October 10
th
, 2016. The minimum score was 30 and the maximum score was 88. There was 1 student who got the score 30. One student got the score 88. Eighteen
students got the score lower than 70 and 10 students got the score higher than 70. The mean of the simple present tense mastery test is 62. It can be seen in appendix 16.
