    Question

    An experimandtal investigation of the relationship betweand Y=prestatieY = prestatie, S=dummyS = dummy seksesekse (meisje=1)(meisje = 1) and G=dummyG = dummy beloningbeloning (wel(wel beloning=1)beloning = 1) levert de volgandde regressievergelijking op:

    Y=18+4S2GY’ = 18+4S–2G.

    Amelie zit in de conditie waarin er wordt beloond and zij heeft eand prestatie van 22.

    Wat is haar voorspelde prestatie and hoe groot is haar residu YiYiY_{i}-{Y}'_{i}?


    1. FALSE: Predicted performance: 18; residue: -2
    2. FALSE: Predicted performance: 20; residue: -2
    3. FALSE: Predicted performance: 18; residue: +2
    4. TRUE: Predicted performance: 20; residue: +2
