  • KESIMPULAN UJI RELIABILITASDari hasil uji ternyata r Alpha (0,785) lebih besar dibandingkan dengan nilai rtabel, maka keempat pertanyaan (P1, P2, P4, P5) dinyatakan reliabel.

    Variabel CronbachsAlpha R tabel Keterangan

    P1 0,785 0,374 Reliabel

    P2 0,785 0,374 Reliabel

    P4 0,785 0,374 Reliabel

    P5 0,785 0,374 Reliabel

    KESIMPULAN UJI VALIDITASAda satu pertanyaan yaitu P3 (r hitung=0,342) yang nilainya lebih rendahdari r tabel (r=0,374), sehingga pertanyaan P3 tidak valid, sedangkanpertanyaan P1, P2, P4 dan P5 valid.
