UKD 2 KORELASI SPEARMAN

Posted: December 14, 2011 in Tugas-Tugas Kuliah (2011-2012)

1. Hitung besarnya koefisien korelasi spearman dari data berikut :

Mahasiswa Kreativitas Mahasiswa Prestasi Mahasiswa Peringkat Kreativitas Mahasiswa Peringkat Prestasi Mahasiswa D
1 40 37 2 2 0 0
2 116 65 8 6 2 4
3 113 88 7 9 -2 4
4 111 86 6 8 -2 4
5 83 56 3 4 -1 1
6 85 62 4 5 -1 1
7 126 92 10 10 0 0
8 106 54 5 3 2 4
9 117 81 9 7 2 4
10 4 4 1 1 0 0
n= 10 ∑D= 0 ∑D²=22

rs = 1 – (6∑D²/n-(n²-1)

rs = 1 – (6.22/10-(10²-1)

rs = 1 – (132/990)

rs = 1 – 0,133

rs = 0,867

2. Hitung besarnya koefisien korelasi spearman dari data berikut :

Dosen Produktivitas Ilmiah Prestasi Mahasiswa Peringkat Produktivitas Ilmiah Peringkat Prestasi Mahasiswa D
1 37 40 2 2 0 0
2 65 116 7 9 -2 4
3 88 113 10 8 2 4
4 54 106 6 6 0 0
5 81 117 8 10 -2 4
6 42 82 4 3 1 1
7 46 98 5 5 0 0
8 39 87 3 4 -1 1
9 86 111 9 7 2 4
10 4 4 1 1 0 0
n=10 ∑D= 0 ∑D²= 18

rs = 1 – (6∑D²/n-(n²-1)

rs = 1 – (6.18/10-(10²-1)

rs = 1 – (108/990)

rs = 1 – 0,109

rs = 0,891
