CIRI-CIRI INSTRUMEN YANG BAIK

• VALIDITAS : MERUPAKAN TINGKAT DIMANA SEBUAH INSTRUMEN MENGUKUR APA YANG BENAR-BENAR INGIN DIUKUR

• KEHANDALAN (RELIABILITAS) : BERKAITAN DENGAN AKURASI DAN PRESISI DARI SEBUAH PROSEDUR PENGUKURAN

• KEPRAKTISAN : BERKAITAN DENGAN KEMUDAHAN PENAFSIRAN.

UJI VALIDITAS

• Pengujian validitas dapat dilakukan dengan dua cara:– Analisis Faktor

Analisis faktor dilakukan dengan cara mengelompokan item pertanyaan menjadi beberapa variabel menggunakan analisisfaktor.

– Analisis Butir

Analisis butir dilakukan dengan mengkorelasikan item pertanyaan dengan jumlah seluruh item pertanyaan
