LAMPIRAN 3 Analisis Validitas Dan Reliabilitas
1. Menentukan validitas aitem
Diketahui T_tabel: 1.69 Maka r tabel =
tabel
=

.
= 0.278 Jadi untuk menentukan validitas suatu aitem, maka nilai aitem tersebut harus diatas 0.278

Aitem yang valid adalah dengan nilai Corrected item-total correlation 0.278 Jadi aitem yang tidak valid adalah nomor 7,11,13,18,23,26,29
Sehingga harus dilakukan uji kedua dengan menghilangkan aitem yang dianggap tidak valid.
