**. Correlation is significant at the 0.01 level (2-tailed).
*. Correlation is significant at the 0.05 level (2-tailed).
SYARAT UJI VALIDITAS Menurut SugiyonoItem soal di katakan valid jika r hitung > 0,3
Item soal di katakan tidak valid/ gugur jika r hitung < 0,3
Nomor R hitung Syarat KeteranganSoal 1 0,907 > 0,3 ValidSoal 2 0,042 < 0,3 Tidak ValidSoal 3 0,907 > 0,3 ValidSoal 4 0,016 < 0,3 Tidak ValidSoal 5 0,267 < 0,3 Tidak ValidSoal 6 0,667 > 0,3 ValidSoal 7 0,042 < 0,3 Tidak ValidSoal 8 0,793 > 0,3 ValidSoal 9 0,907 > 0,3 ValidSoal 10 0,907 > 0,3 Valid
Dari hasil uji Validitas, dapat disimpulkan bahwa :
- Item soal nomor 2, 4, 5 dan 7 dinyatakan tidak valid sehingga harus diganti atau dibuang.- Item soal Nomor 1, 3, 6, 8, 9, dan 10 dinyatakan valid sehingga bisa digunakan

R hitung
Syarat Keterangan
Soal 1 0,543 >0,6 Tidak Reliabel
Soal 2 0,793 >0,6 ReliabelSoal 3 0,543 >0,6 Tidak ReliabelSoal 4 0,729 >0,6 ReliabelSoal 5 0,716 >0,6 ReliabelSoal 6 0,597 >0,6 Tidak ReliabelSoal 7 0,739 >0,6 ReliabelSoal 8 0,561 >0,6 Tidak ReliabelSoal 9 0,543 >0,6 Tidak ReliabelSoal 10 0,543 >0,6 Tidak Reliabel
Dari analisis data uji Reliabilitas dapat disimpulkan, bahwa :
Hanya 4 soal yang reliabel
Kriteria reliabilitas didapatkan dari Croanbach’s Alpha adalah apabila didapatkan nilai Croanbach’s Alpha kurang dari 0,600 berarti buruk, sekitar 0,700 diterima dan lebih dari atau sama dengan 0,800
adalah baik.
