    Question

    ANOVA is a multiple regression with a quantitative dependent variable and categorical (indicator) variables. The null hypothesis of a one-way (one factor) three-level ANOVA is that the averages of all three groups (populations) are equal. In the multiple regression represents the null hypothesis that the plane through the averages of the three groups is horizontal. The null hypothesis of the multiple regression which is equivalent to that of ANOVA is


    1. FALSE: H0: β1 = β2
    2. TRUE: H0: β1 = β2 = 0
    3. FALSE: H0: β1 = β2 = α

    1. H0: β1 = β2: Incorrect
    2. H0: β1 = β2 = 0: Correct
    3. H0: β1 = β2 = α: Incorrect
