Referring to the Table 4.4 there were nine students 20 came in the category of very good. There were also nine students 20 were on the category of good. On
the other hands, seven students 15.56 were on the category of sufficient. In addition, there were three students 6.67 came into category of insufficient. The
rest of the students in which there were 17 students 37.78 came in the category of poor. Based on the category, 25 students 55.56 of the total students passed
the test. On the other hand, 20 students 44.44 of the total students failed on the test because of their final scores did not reach the category of sufficient. In
addition, descriptive statistics revealed the students’ performance in general and described the distribution of the score.
2. The Presentation of the Descriptive Statistics
Brown 2005: 97 describes descriptive statistics as numerical representation on the students’ performance on a test. Furthermore, Brown
explains that descriptive statistics can create a mental picture of how the students performed on the test. Therefore, by reviewing the descriptive statistics of the test,
the students’ typical performance and its variations could be overviewed. The complete variables and values of the descriptive statistics of the students test are

The table presents that 45 students joined the test which consisted of two subtests. The test consisted of 12 items in which part A consisted of 10 items and
part B consisted of two items. The result of the test revealed that the mean was 57.77. Based on the academic regulations, students’ performance was considered
sufficient. The value which occurred most frequently or the mode was 40. The test revealed that seven students achieved this score. Furthermore, the median of the
test result was 60. In addition, the midpoint of the test score was 62.5. On the other hands, the range of the scores was 76. Finally, the standard deviation which
revealed the spread and the volatility of the scores Ary et al., 2002: 135 and Gay, 1992: 393 was 21.07. Similarly, Brown 2005: 103 explains that standard
deviation is a sort of average of the differences of all scores from the mean. The standard deviation 21.07 of the entire test revealed that the dispersion of the
students’ scores from the mean was around that number. The followings are the complete discussions of the students’ performance
on analysing the adjective clauses using the X schema. Besides, it also presents the general classifications of the students’ mistakes on the test. Related theories
and the students’ performance are contrasted to elicit the research findings. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI

B. Discussion
This part deals with answering the research questions. The research questions were 1 What is the sixth semester students’ performance on analysing
the adjective clauses using the X-Bar schema? and 2 What are the general classifications of the most mistakes commonly made by the students on analysing
the adjective clauses using the X-Bar schema? The discussion on those two questions are based on the students’ work and related theories.
1. The Students’ Performance on Analysing the Adjective Clauses using the X-Bar Schema
The result of the test showed that the students’ performance was considered sufficient in that the students achieved the average score 57.77 on
the test. In details, the mean of the scores in the first part of the test was 64.67 whereas the second part of the test was 50.89. Considering the academic
regulation of Sanata Dharma University, both the first part and the second part of the test came in the group of sufficient. By looking at the Table 4.1, 4.2 and 4.3,
the students’ performance in each part of the test was elaborated in details. In addition, the objective of the test was to measure the students’
performance on the concepts and theories of the adjective clauses and the X schema. The concepts and theories tested in this part were main clause, dependent
clause, modifier, head, I, inflection phrase, complementizer phrase, Wh movement, trace and tree diagram. In order to be able to do the test, the students
should master those concepts and theories thoroughly. However, they should also PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
