Week 3 Group Differences Design Tree Flashcards
To be able to review research design and decision tree for choosing your analytical technique.
When there is One (Continuous) Dependent Variable (DV), what is the purpose of testing the significance of group differences?
The goal of analysis is to determine the reliability of mean group differences
If you are wanting to study the significance of group differences and had one DV, one IV, with no covariates, which test would you run? and again with one or more covariates?
1 x DV & 1 x IV & 0 covariates: a one way ANOVA or a t-test
with one or more covariates: a one way ANCOVA
If you are wanting to study the significance of group differences and had one DV, multiple (discrete) IVs, with no covariates, which test would you run?and again with one or more covariates?
1 x DV & multiple x IV & 0 covariates: a factorial ANOVA
with 1 x DV & multiple x IV & 1+ covariates: a factorial ANCOVA
When there are multiple (Continuous) Dependent Variables (DV’s), what is the purpose of testing the significance of group differences?
The goal of analysis is to create a linear combination of the DV’s to maximise mean group differences
If you are wanting to study the significance of group differences and had multiple (Continuous) DV’s, one (discrete) IV, with no covariates, which test would you run? and again with one or more covariates?
multiple DV’s & 1 IV & 0 covariates = One-way MANOVA
multiple DV’s & 1 IV & 1+ covariates = One-way MANCOVA
If you are wanting to study the significance of group differences and had multiple (Continuous) DV’s, multiple (discrete) IV’s, with no covariates, which test would you run? and again with one or more covariates?
multiple DV’s & multiple IV’s & 0 covariates = Factorial MANOVA
multiple DV’s & Multiple IV’s & 1+ covariates = Factorial MANCOVA
What is the purpose of testing the significance of group differences when using Profile Analysis?
The goal of analysis is to create a linear combination of the DV’s to maximise mean group differences AND differences between levels of within subjects IV’s
If you are wanting to study the significance of group differences and had one (Continuous) DV, multiple (discrete) IV’s within S, with no covariates, which test would you run?
1 x DV & multiple IV’s within S = Profile Analysis of Repeated Measures
If you are wanting to study the significance of group differences and had multiple (Continuous or commensurate) DV’s, and one (discrete) IV’s, with no covariates, which test would you run?
Multiple continuous or commensurate DV’s & 1 x IV’s within S (No Covariates)= Profile Analysis of Repeated Measures
If you are wanting to study the significance of group differences and had multiple (Continuous) DV’s, and multiple (1 discrete within S) IV’s, with no covariates, which test would you run?
Multiple continuous DV’s & multiple (1 discrete within S) x IV’s (No Covariates) = Doubly Multivariate Profile Analysis
