    Question

    An experimental investigation of the relationship between Y = achievement, S = dummy gender (girl=1) and G = dummy reward (well reward=1) yields the following regression equation: Y’=20+6S–4G{Y}’ = 20+6S–4G. Hanneke is in the condition where there are rewards and she has a performance of 23. What is her predicted performance and how big is her residue Yi−Y′iY_{i}-{Y}'_{i}?


    1. FALSE: Predicted performance: 22 ; residue: -1
    2. FALSE: Predicted performance: 23 ; residue: -2
    3. TRUE: Predicted performance: 22 ; residue: +1
    4. FALSE: Predicted performance: 23 ; residue: +2
