5. Example For Norm Reference Test
Sekelompok mahasiswa terdiri dari 40 orang dalam
satu ujian mendapat nilai mentah sebagai berikut:
55 43 39 38 37 35 34 32
52 43 40 37 36 35 34 30
49 43 40 37 36 35 34 28
48 42 40 37 35 34 33 22
46 39 38 37 36 34 32 21
7. Jika skor mentah yang paling tinggi (55) diberi nilai 10
maka nilai untuk :
52 adalah (52/55) x 10 = 9,5
49 adalah (49/55) x 10 = 9,0 dan seterusnya
8. Example for Criteration Test
Dalam menginterpretasi skor mentah menjadi nilai dengan
menggunakan pendekatan criteration maka terlebih dahulu
ditentukan kriteria kelulusan dengan batas-batas nilai
kelulusan. Umumnya kriteria nilai yang digunakan dalam
bentuk rentang skor berikut:
Rentang Skor Nilai
80% s.d. 100% A
70% s.d. 79% B
60% s.d. 69% C
45% s.d. 59% D
< 44% E / Tidak lulus
9. A memperoleh skor 24
Criteria maksimum yang diharapakan 40
Sehingga menjadi
24/40 X 100% =60 %
Kita lihat Dalam daftar rentang skor nilai 60 berada
pada point C
