    4. DMatrix of ANalyses Of Variance
    5. EMultivariate ANalyses Of VAriance
    6. FMy ANOVA
  2. 2Basic requirements to run MANOVA:
    1 or more [blank_start]____________[blank_end] [blank_start]____________[blank_end] variable(s)
    2 or more [blank_start]____________[blank_end] [blank_start]____________[blank_end] variable(s)
    1. ACategorical
    2. BIndependent

  3. 3Assumptions of MANOVA:
    Homogeneity of covariance matrices – same as for ANOVA plus correlations between any DVs is the same in each group.
    Independence – observations [blank_start]____________[blank_end] be statistically independent.
    Multivariate normality – DVs collectively have multivariate normality [blank_start]____________[blank_end] groups.
    Random sampling – data should be randomly sampled from population of interest.
    1. AShould
    2. BNeed not
    3. CWithin
    4. DBetween
  4. 4DVs = ?
    1. ADependent Variables

  5. 5Multivariate normality assumes that the means of the various [blank_start]____________[blank_end] variables in each cell and all linear combinations of them are normally distributed.
    1. ADependent
    2. BIndependent
  6. 6Shapiro-Wilks test is used to test for:
    1. ANormality
    2. BCorrelation
