  • 21. Interpretasi Data Uji Normalitas Kolmogorov-Smirnov
  • 22.
    • Penjelasan
    • Uji tes KS (Kolmogorov-Smirnov) Test dan Histogram
    • a. Semua variabel menunjukkan nilai signifikansi probabilitas
    • dibawah α = 0,05, hal ini berarti hipotesis nol ditolak atau
    • tidak terdistribusi secara normal,
  • 23. Hubungan antar variabel Hubungan korelasi rendah : Transportation(1)(2) Vs Residential(1)(2) Transportation(1)(2) Vs AllSector(1)(2) Transportation(1)(2) Vs Commercial(1)(2) Transportation(1)(2) Vs Industry(1)(2)
    • Ket:
    • = 2005
    • = 2004
    Hubungan korelasi tinggi : Residential (1)(2) Vs AllSector(1)(2) Residential (1)(2) Vs Commercial(1)(2) Industrial (1)(2) Vs Commercial(1)(2) Transportation(1)(2) Vs Industry(1)(2)
  • 24. Analisis Faktor Hasil KMO and Bertlett test (nilainya di atas 0,5), maka dapat dilakukan analisa faktor
  • 25. Dari 10 variabel yang dianalisa ternyata hasil ekstrasi komputer menjadi 2 faktor (nilai eigen > 1 menjadi faktor), Dimana faktor 1 mampu menjelaskan 76,431% variasi, sedangkan faktor 2 mampu menjelaskan 18,748% variasi, atau kedua faktor keseluruhan mampu menjelaskan 95,178% variasi
  • 26. Yang mengelompok pada faktor 1 : Residential (1) (2), Commercial (1) (2), Industrial(1) (2) dan AllSector (1) (2) Yang mengelompok pada faktor 2 : Transportation (1) (2)
