Within the variability explained by SSm, how can we further split the variance in an independent measures factorial ANOVA?

Selecciona una de las siguientes respuestas posibles:

You cannot further split the variance explained by SSm
The variance explained by SSm is made up of only the SS for each variable
The variance explained by SSm is made up of the SS for each variable plus the SS for the interactions
The variance explained by SSm is made up of the MS for each variable plus the MS for the interactions

I have two factorial IV's: Age and gender. How do we look at the main effect of age?

Selecciona una de las siguientes respuestas posibles:

We average across all levels of gender and only look at the differences in age groups
We average across all levels of age and only look at the differences in age group
We average across all levels of age and only look at the different levels of gender groups
We average across all levels of gender and only look at the differences in gender

Following from the previous question, I have calculated SSage and SSgender. How do I calculate SSage*gender. What does this tell me?

Selecciona una de las siguientes respuestas posibles:

After calculating SSage and SSgender then the remaining variance accounted for by SSt is the variance from SSage*gender. This is the interaction between the two variables
After calculating SSage and SSgender then the remaining variance accounted for by SSm is the variance from SSage*gender. This is the main effect of the two variables
After calculating SSage and SSgender then the remaining variance accounted for by SSm is the variance from SSage*gender. This is the interaction between the two variables
You do not get SSage*gender in independent samples factorial ANOVA

What is an interaction?

Selecciona una de las siguientes respuestas posibles:

When both IV's have a main effect
When the effect of one DV on the IV is dependent on another DV
When the effect of one IV on the DV is dependent on another IV
When both DV's have a main effect

The following graph summarises the interaction effect of age and gender on colour perception test scores (DV). What does this interaction show?

Selecciona una de las siguientes respuestas posibles:

Colour perception improvement with age did not differ both boys and girls. For both genders, colour perception was better for 11 year olds compared to five year olds.
Colour perception improvement with age differed between boys and girls. For boys, no difference in colour perception was found between 5 year olds and 11 year olds. However, for girls there was an effect of age on colour perception.
Colour perception improvement with age did not differ both boys and girls across the ages. For both genders, colour perception was better for 5 year olds compared to 11 year olds.
Colour perception improvement with age differed between boys and girls. For girls, no differences in colour perception were found between 5 year olds and 11 year olds. However, for boys there was an effect of age on colour perception.

As my study is a factorial between subjects design, the relevant assumption I should be concerned about is ___. If this assumption is met, I would expect to see that _.

Selecciona una de las siguientes respuestas posibles:

Homogeneity of variance; the Levene's test should not be significant.
Sphericity; the Mauchly's test should be significant.
Sphericity; the Mauchly's test should not be significant.
Homogeneity of variance; the Levene's test should be significant.

After completing our factorial ANOVA, why do we need to test the simple effects?

Selecciona una de las siguientes respuestas posibles:

Because we want to examine the differences between the IV's
To understand the effects of the individual variables
You don't need to do this as it shows the same as the main effects
Because this is the best way to explain an interaction, if the interaction exists.

Why can't we only interpret the F-value from the SSm (i.e. "Corrected Model) line of output?

Selecciona una de las siguientes respuestas posibles:

Because we don't just need to know how much variance is explained by the model, but whether each individual variable and their interactions is explaining a significant amount of the variance
Because we need to know how much variance is explained by the SSr output, which is part of the variance explained by SSm
Trick question - we only interpret the SSm line of output in factorial ANOVA
Because we don't just need to know how much variance is explained by the model, but whether each individual variable is explaining a significant amount of the variance
