a. Perhitungan Sampel Total
Persamaan yang digunakan untuk menghitung sampel adalah Rumus
Isaac dan Michael sebagai berikut: � =
�
2
. �. .
�
2
� − 1 + �
2
. . Keterangan:
s = jumlah sampel N =jumlah populasi
χ
2
= chi kuadarat dengan dk =1, taraf kesalahan 5 d = 0,05
P = Q = 0,5 -
Sehingga diketahui : N = 149
�
2
= 3,841 d = 0,05
P =Q =0,5 -
Maka jumlah sampel s adalah: � =
3,841.149.0,5.0,5 0,05
2
149 − 1 + 3,841.0,5.0,5 � =
117,15 0,30 + 0,960
� = 92,97 Dibulatkan menjadi 93 responden
b. Perhitungan Sampel Tiap Sekolah
Untuk menghitung sampel pada masing-masing sekolah yang berproporsi maka digunakan rumus sebagai berikut:
Sampel tiap sekolah = populasi tiap sekolahpopulasi totalsampel total
107
1. Kelas XII TITL 1 = 3212293 = 24 siswa 2. Kelas XII TITL 2 = 3012293 = 23 siswa
3. Kelas XII TITL 3 = 3012293 = 23 siswa 4. Kelas XII TITL 4 = 3012293 = 23 siswa
