In a mixed factorial ANOVA, with respect to assumptions, are we concerned with Homogeneity of variance or Sphericity?Both, but assumption of sphericity only applies when the within subjects IV has 3+ levels as with repeated measures designs that are not mixed.Assumption of sphericity only, which applies when the within subjects IV has 2+ levels as with repeated measures designs that are not mixed.Assumption of sphericity only, which applies when the within subjects IV has 3+ levels as with repeated measures designs that are not mixedHomogeneity of variance only

Which of the following statements about the assumption of sphericity is NOT true?It is automatically met when an independent variable has only two levelsIt is the repeated measures equivalent of homogeneity of variancesIt is tested using Mauchley's test in SPSSIt is tested using Levene's test in SPSSQuestion 9

Which of these are the assumptions that form the bedrock of an analysis of variance (ANOVA)? Choose three.Answer instructionsThe populations have different variances.The populations have the same variance.The observations are independent of each other.The observations are dependent on each other.The observations are random samples from normal distributions.The observations are normal samples from random distributions.

Identify the four research situations using ANOVA to test the null hypothesis.Select one or more:a.two-factor analysis for independent groups designsb.single-factor analysis of dependent groupsc.multiple-factor analysis for mixed designsd.single-factor analysis for repeated measures designse.two-factor analysis for dependent groups designsf.two-factor analysis for mixed designsg.single-factor analysis of independent groups designs

ANOVA assumes that the data meets the following assumptions

Different levels of a factor in an ANOVA procedure is called
