MANAKAH PERNYATAAN YANG BENAR?
Analisis regresi dan korelasi digunakan untuk memahami hubungan antara dua variabel kuantitatif. Regresi linear sederhana memprediksi nilai variabel dependen berdasarkan satu variabel independen. Koefisien korelasi (r) menunjukkan arah dan kekuatan hubungan linear, sedangkan koefisien determinasi menunjukkan seberapa besar variasi data yang bisa dijelaskan oleh model.
Regresi dan korelasi hanya dapat digunakan pada data kategorik. Nilai koefisien korelasi yang mendekati 0 menunjukkan hubungan yang sangat kuat. Koefisien determinasi tidak penting karena tidak memberikan informasi apa pun tentang model. Dalam regresi, semakin besar nilai residual, semakin baik modelnya.
