    Question

    Om 4 behandelingen (1, 2, 3, en 4) met elkaar te vergelijken op gemiddelde effectiviteit worden in 5 klinieken (A, B, C, D en E) 4 personen door loting over de behandelingen verdeeld. De gegevens worden m.b.v. ANOVA geanalyseerd. Welke nulhypothese kan hier zinvol getoetst worden?


    1. TRUE: μ1 = μ2 = μ3 = μ4
    2. FALSE: μA = μB = μC = μD = μE
    3. FALSE: σ21 = σ22 = σ23 = σ24
    4. FALSE: σ2A = σ2B = σ2C = σ2D = σ2E

    1. μ1 = μ2 = μ3 = μ4: Correct
    2. μA = μB = μC = μD = μE: Incorrect
    3. σ21 = σ22 = σ23 = σ24: Incorrect
    4. σ2A = σ2B = σ2C = σ2D = σ2E: Incorrect
