    What is ANOVA used for?

    Compares three or more groups of conditions.

    What distinguishes a one-way ANOVA from a two-way ANOVA?

    One-way has one independent variable; two-way has two.

    What does a two-way ANOVA analyze?

    Interactions between two independent variables.

    What are the two types of variance in ANOVA?

    Between-group variance and within-group variance.

    What is a factorial design?

    Combines multiple independent variables to assess their effects.

    How many conditions are in a 2x2 design?

    Four conditions total.

    What is the dependent variable in ANOVA?

    It is continuous.

    What happens if you have two independent variables in ANOVA?

    You can assess their combined effects on the dependent variable.

    What is the implication of having categorical independent variables?

    They define distinct groups for comparison.

    What does measuring the DV in each condition reveal?

    Differences in outcomes based on independent variable levels.

    What is Two-way ANOVA used for?

    Analyzing the effect of two independent variables on a dependent variable.

    What does a 2x3 design indicate?

    It has two independent variables with 2 and 3 levels, resulting in 6 conditions.

    What are IVs in Two-way ANOVA?

    Factors that influence the dependent variable.

    What is a main effect in Two-way ANOVA?

    The effect of one independent variable regardless of the other.

    How does interaction differ from main effects?

    Interaction shows how the effect of one IV changes at different levels of another IV.

    What is the null hypothesis for the first independent variable?

    The means of all groups are equal.

    What does the interaction hypothesis test?

    Whether there is an interaction between the two independent variables.

    What is the dependent variable in the food preference study?

    The muscle activity in dogs' faces.

    What does a significant main effect of Attention Presence indicate?

    Greater muscle activity occurs with human attention compared to without.

    What is a cross-over interaction?

    The effect of one IV changes direction at different levels of another IV.

    What are the assumptions of Two-way ANOVA?

    Normality, homogeneity of variance, independence of observations, and sphericity.

    Why are degrees of freedom important in ANOVA?

    They are used to calculate mean variance scores for the F-ratio.

    What does a significant interaction between Location and CCTV presence suggest?

    CCTV affects feelings of safety differently based on location.

    What is the effect of Time of Day in the food preference study?

    It influences food preference regardless of food flavor.

    What does the term 'Estimated Marginal Means' refer to?

    The average predicted values for each level of an independent variable.
