Attachment style
The adjusted group mean for the DV has been adjusted to standardize it with the other groups based on the grand mean for the covariate.
Look at the output on p. 470. What is the overall effect of age?
Consider the output displayed on p. 470. What is the F-Value associated with the effect of age?
Consider the study in question 2. Which of the below questions would be pertinent to this analysis?
What would the degrees of freedom be if you were reporting the results of the effect of Age from the output on p. 470?
Using the example in the text book (which begins on p. 471), which variable is the covariate in this study?
Look at the output on p. 470. What is the overall effect of the grouping?
What are the two main reasons for using ANCOVA?
You are conducting a study. The IV is attachment style. There are three groups of individuals with different attachment styles; these are secure, dismissing, and fearful. You want to explore whether these differ on their scores of relationship satisfaction. The DV is relationship satisfaction. You are aware, however, that relationship satisfaction is known to co vary with depression. You conduct an ANCOVA with this data. The formula will remove the variance due to the association between which two variables?
In the example in question 12 there are 3 groups to consider. If you found that the groups differed significantly on reading ability, what might you use to further explore these group differences?
