Week 3 Group Differences Design Tree Flashcards

To be able to review research design and decision tree for choosing your analytical technique.

1
Q

When there is One (Continuous) Dependent Variable (DV), what is the purpose of testing the significance of group differences?

A

The goal of analysis is to determine the reliability of mean group differences

Q

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?

A

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

Q

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?

A

1 x DV & multiple x IV & 0 covariates: a factorial ANOVA

with 1 x DV & multiple x IV & 1+ covariates: a factorial ANCOVA

Q

When there are multiple (Continuous) Dependent Variables (DV’s), what is the purpose of testing the significance of group differences?

A

The goal of analysis is to create a linear combination of the DV’s to maximise mean group differences

Q

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?

A

multiple DV’s & 1 IV & 0 covariates = One-way MANOVA

multiple DV’s & 1 IV & 1+ covariates = One-way MANCOVA

Q

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?

A

multiple DV’s & multiple IV’s & 0 covariates = Factorial MANOVA

multiple DV’s & Multiple IV’s & 1+ covariates = Factorial MANCOVA

Q

What is the purpose of testing the significance of group differences when using Profile Analysis?

A

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

Q

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?

A

1 x DV & multiple IV’s within S = Profile Analysis of Repeated Measures

Q

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?

A

Multiple continuous or commensurate DV’s & 1 x IV’s within S (No Covariates)= Profile Analysis of Repeated Measures

Q

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?

A

Multiple continuous DV’s & multiple (1 discrete within S) x IV’s (No Covariates) = Doubly Multivariate Profile Analysis
