2x2 BG ANOVA & 2x2 MG ANOVA
If we had 40 total participants in a study, n would be 10 for a __________ factorial design, n would be 40 for a __________ factorial design and n would be 20 for a __________ factorial design.
BG; WG; MG
__________ are used to test if main effects and interactions are significant, while __________ are used to determine if the main effects are descriptive and to describe the pattern of a significant interaction.
F-tests; LSDmmd tests
__________ factorial designs have different participants in each design cell, __________ factorial designs have each participant in all design cells, and __________ factorial designs have each participant in two of the design cells.
WG; BG; MG
__________ main effect interpretations are always appropriate, while __________ main effect interpretations require that the conditions of that IV were randomly assigned, properly manipulated and there was good experimental control.
associative; causal
__________ main effect interpretations only say whether or not there is a statistical relationship between one IV and the DV, while __________ main effect interpretations also say that the DV value is a direct result of the value of that IV.
associative; causal
__________ IVs involve having different participants in the different conditions of the IV, while __________ IVs involve having the same participants in all conditions of the IV.
between groups; within groups
__________ IVs require a between groups F-test of their main effect, while __________ IVs require a within-groups F-test of their main effect.
between groups; within groups
Describe how each "effect" in a 2x2 factorial design is statistically examined.
corresponding significance test
A RH: about whether or not there is an interaction is tested by a/an __________, while a RH: about the pattern of that interaction is tested by a/an__________.
interaction F-test; simple effects LSDmmd test
A/an __________ is used to determine if there is an interaction, while a __________ is used to determine the pattern of a significant interaction.
interaction F-test; simple effects LSDmmd test
__________ F-tests are used to determine if a single IV is related to the DV, while __________ F-tests are used to determine if the combination of IVs is related to the DV.
main effect; interaction
__________ F-tests tell if the marginal means of one IV are significantly different, while __________ F-tests tell if the simple effects of one IV are significantly different at different levels of the other IV.
main effect; interaction
__________ F-tests compare marginal means, while __________ tests compare cell means.
main effect; simple effect
RH: about marginal means are tested using __________, while RH: about the pattern of an interaction are tested using __________
