Question
Below are the results of a stepwise regression analysis. The dependent variable “PINC” is personal monthly income (net, in euros). “AGE” is a person’s age in years; “HIGHEDUC” is a dummy variable (highly educated = 1; not highly educated =0); Highly educated implies that a person has completed a college or university level education completed or is currently pursuing such an education. “AGE_HIGHEDUC” is a multiplicative interaction term of the variables “AGE” and “HIGHEDUC”.
Study the regression model with the interaction term (Model 3).
Suppose we compare two highly educated individuals, Boris and Donald. Boris is 1 year older than Donald. How much higher is the estimated monthly income of Boris compared to Donald?
And now suppose we compare two lowly educated individuals compare, Angela and Mark. Angela is 1 year older than Mark. How much higher is Angela’s estimated monthly income compared with Mark?
- TRUE: Boris earns 22,592 euros (2,430 + 20,162) more than Donald. And Angela earns 2,430 euros more than Mark.
- FALSE: Boris earns 20,162 euros more than Donald. And Angela earns 2,430 euros more than Mark.
- FALSE: Boris earns 20,162 euros more than Donald. And Angela earns 17.732 (20.162 – 2.430) euros more than Mark.
- FALSE: Boris earns 22,592 euros (2,430 + 20,162) more than Donald. And Angela earns 17,732 (20,162 – 2,430) euros more than Mark.
