In a TWO-factor Analysis of Variance, total variance is partitioned into which of the following? (Look carefully at all the subscripted notations.)

  1. SStotal = SSa + SSb + SSwithin

    SStotal = SSa + SSb + SSab

    SStotal = SSab + SSwithin

    SStotal = SSbetw + SSab

    SStotal = SSa + SSb + SSab + SSwithin

  1. In a two-factor ANOVA, an interaction occurs whenever the effect of one factor:

    is found to be significant.

    is weaker than the effect of another factor.

    is consistent across all levels of another factor.

    differs depending on the level of another factor.
