**. Correlation is significant

|||||||
Nilai signifikansi 2 tale < 0,05 maka dikatakan
valid
Artinya item pertanyaan tersebut valid, atau
pertanyaan tersebut dapat digunakan untuk mengukur variabel
Pertanyaan kuesioner dapat terkait dengan variabel
yang digunakan, misal pertanyaan mengenai insentif terkait dengan besaran
insentif telah sesuai, insentif diberikan secara adil
Menggunakan nilai r hitung > r tabel
Jumlah sample sebanyak 60, maka df = (n-2), df =
58 sehingga r tabel sebesar 0,2542
Berdasarkan tabel di atas keseluruhan r hitung
> r tabel, maka dengan metode kedua semua instrumen dinyatakan valid
