Semester : V/A

Tugas : Teknik Analisis dan Penyajian Data Epidemiologi

Contoh Kasus:

Saya melakukan penelitian dengan menggunakan skala untuk mengetahui atau mengungkap Pengaruh

Stigmatisasi dan Diskriminasi Masyarakat Terhadap Penderita HIV dan AIDS. Saya membuat 20 butir

pertanyaan dengan menggunakan skala Guttman, yaitu angka 1 = Ya, dan angka 2 = Tidak. Setelah

membagikan skala kepada 15 responden didapatlah tabulasi data-data sebagai berikut:

Dengan menggunakan program SPSS, maka teknik pengujian yang digunakan untuk uji validitas

kuesioner adalah menggunakan korelasi Bivariate Pearson (Produk Momen Pearson) dan memperoleh hasil

analisis sebagai berikut :

Dari hasil analisis didapat nilai korelasi antara skor item dengan skor total. Nilai inikemudian dibandingkan dengan nilai r tabel, r tabel dicari pada signifikansi 0,05 dengan uji 2sisi dan jumlah data (n) = 15, maka didapat r tabel sebesar 0,514.

Berdasarkan hasil analisis di dapat nilai korelasi untuk item 5, 7, 8, 9, 10, 11, 14, 15, 16,17, 18, 19 dan 20 nilai kurang dari 0,514. Karena koefisien korelasi pada item 5, 7, 8, 9, 10,

11, 14, 15, 16, 17, 18, 19 dan 20 nilainya kurang dari 0,514 maka dapat disimpulkan bahwa item-item tersebut tidak berkorelasi signifikan dengan skor total (dinyatakan tidak valid) sehinggaharus dikeluarkan atau diperbaiki. Sedangkan pada item-item lainnya nilainya lebih dari 0,514dan dapat disimpulkan bahwa butir instrumen tersebut valid.
