4.5 The Descriptive Statistics

No. Variables Score 1. Mean 15.46 2. Median 16 3. Mode 18 4. Range 14 5. Standard Deviation 15.54 From the table above, the average score mean the students achieved in the test is 15.46. This score shows the students mastery in the use of passive voice. To determine the students’ mastery in the use of passive voice, the writer referred to the academic regulation of Sanata Dharma University. There are three measurement systems that can be used to determine the students’ mastery on certain material Peraturan Akademik 1998:14. The first is the Sistem Penilaian Acuan Patokan or PAP Criterion-referenced measurement systems. With this system, firstly we have to determine the minimum passing score as the minimum standard of mastery the students must achieve. The second is Sistem Penilaian Acuan Norma or PAN Norm- referenced measurement systems. In this system, the students’ achievement is 38 compared to expected achievement, then the minimum passing group is determined. The measurement system that is suitable with the Communicative approach and is used in Sanata Dharma University is the adjusted criterion-referenced measurement system. This system requires the teacher to first determine the minimum passing score as the minimum standard of mastery. The minimum passing score is 56 of the highest score the students can achieve in the test. The students who achieve 56 of the highest score enter the category of sufficient C. If the students can only achieve 50 of the highest score, then they fall on the category of insufficient. The minimum score for the category good B and very good A are determined by the teacher by considering the score distribution above the minimum passing score 56. Referring to the academic regulation above, the writer then set the score category that was applied in this study. The highest score the students could achieve in the test was 20. The 56 of this score is 11. This is the minimum passing score. If the students’ score fall among 9-12, it means they enter the category of sufficient C. The following is the score category. Score Category 17-20 Very good 13-16 Good 9-12 Sufficient 5-8 Insufficient 4 fail 39 The students’ average mean score was 15.46. This score fell on the category of good. Obviously, the second semester students’ mastery in the use of passive voice was considered good according to the academic regulation of Sanata Dharma University. The table below presents the students’ score in relation to the category.
