Module 3, Lecture 5,
Outline (for MANOVA part):
• MANOVA
o Uses in ecology
o Comparison to ANOVA
o Process and theory underpinning it
o Choosing a test statistic
o Corrections for multiple comparisons?
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)
Responda
Categorical
Independent
Dependent
Continuous
Questão 3
Questão
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.
Responda
Should
Need not
Within
Between

Questão 5
Questão
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.
Responda
Dependent
