1.       Hypotesis :

Ho  : Variabel X tidak bersifat linear terhadap variabel Y 

Ha  : Variabel X bersifat linear terhadap variable Y

 

2.       Syarat penarikan kesimpulan :

Fhitung > Ftabel ; maka , Ho ditolak

Fhitung ≤ Ftabel ; maka , Ha diterima

 

3.       Mencari nilai Fhitung ;

-          Nilai dari ; JKreg(a) = (∑Y)2 / n = (862)2 / 12 = 61920,3

 

-          b = (n.∑XY - ∑X.∑Y)/(n. ∑X2 – (∑X)2)) = (12(3101) – (40.862))/12(158) – (40)2 = 1,93

 

-          JKreg a(b/a) = b(∑XY – (∑X. ∑Y/n)) = 9,3 (3102 – (40.862)/12) = 2119,8

 

-          JKres = ∑Y2- (JKreg a(b/a) + JKreg(a)) = 64292 – (61920,3 + 2119,8) = 251,9

 

-          RJKreg(b/a) = JKreg(a) = 61920,3

 

-          RJKreg(b/a) = JKreg(b/a) = 2119,8

 

-          RJKres = JKres / n-2 = 251,9 / 12-2 = 25,2

 

Fhitung = RJKreg(b/a) / RJKres = 2119,8 / 25,2 = 84,1

 

4.       Nilai dari Ftabel ; dengan tingkat kesalahan ; α = 5%

5.       Ftabel = F ((1- α )(dkreg(b/a),(dk res)) = F(0,95)(1,10) = 4,96

Syarat Penarikan Kesimpulan ;

Fhitung > Ftabel = 84,1 > 4,96  maka ; Ho ditolak ; artinya data var (x) bersifat linear terhadap var (y)
