Denne testen tester den trivariate modellen (kjønn, utdanning) opp mot den bivariate<br />
modellen (bare kjønn som uavhengig variabel).<br />
H 0 : Den nye variabelen vi har inkludert representerer ingen forbedring i forhold til vår<br />
tidligere modell med færre variable.<br />
I modellen med kun én uavhengig variabel er -2LL = 2846.106<br />
I den trivariate analysen er -2LL = 2734.293<br />
Differansen er 111.812<br />
Df = 1 siden forskjellen på de to modellene er 1 variabel<br />
Kritisk verdi: 3.84<br />
Konklusjon: Den fulle modellen gir et signifikant forklaringsbidrag i forhold til en<br />
modell med bare én uavhengig
