Question 1

Question
What is a MANOVA?
Answer
  • Multivariate ANalysis Of VAriance
  • Multidimensional ANalysis Of VAriance
  • Multiple ANalyses Of VAriance
  • Matrix of ANalyses Of Variance
  • Multivariate ANalyses Of VAriance
  • My ANOVA

Question 2

Question
Basic 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)
Answer
  • Categorical
  • Independent
  • Dependent
  • Continuous

Question 3

Question
Assumptions 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.
Answer
  • Should
  • Need not
  • Within
  • Between

Question 4

Question
DVs = ?
Answer
  • Dependent Variables
  • Domestic Violence ...s

Question 5

Question
Multivariate 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.
Answer
  • Dependent
  • Independent

Question 6

Question
Shapiro-Wilks test is used to test for:
Answer
  • Normality
  • Correlation

Question 7

Question
The following: - Hotelling’s Trace - Pillai’s Trace - Roy’s Largest Root - Wilk’s Lambda are all what?
Answer
  • Multivariate test criteria for MANOVA
  • Multivariate test criteria for ANOSIM
  • Multivariate test criteria for PERMANOVA
  • Multivariate test criteria for ANOVA
  • Multivariate test criteria for nMDS
  • Multivariate test criteria for SIMPER
