Dari hasil perhitungan tersebut dapat diketahui bahwa maka persamaan garis regresi adalah
Y=β0+β1X = 48,737+4,318X
Ini berarti bahwa :
a.
Nilai
rerata GDP ketika IMT=0 adalah 48,737
b.
Setiap
kenaikan IMT sebesar 1 maka akan terjadi kenaikan GPP sebesar 4,318 mg/dl
c.
Misalkan,
jika seseorang mempunyai IMT 22,5, maka prediksi GPPnya adalah
48,737+4,318X = 48,737+4,318
(22,5) = 145,9 mg/dl

Dari hasil perhitungan tersebut dapat diketahui bahwa maka persamaan garis regresi adalah
Y=β0+β1X =
76,206 + 4,504X
Ini berarti bahwa :
a. Nilai rerata Trigliserida ketika IMT=0 adalah 76,206 mg/dl
b. Setiap kenaikan IMT sebesar 1 maka akan terjadi kenaikan
kadar trigliserida sebesar 4,504 mg/dl
c. Misalkan, jika seseorang mempunyai IMT 22,5, maka prediksi
kadar trigliseridanya adalah 76,206 + 4,504X = 76,206 + 4,504(22,5) = 177,546
