Answer to Question 2

When a hierarchical regression analysis suggests moderation, meaning that the addition of the interaction term(s) contributes significantly to the improvement in R2 and therefore the model
F, the best way to interpret the result is using a graphical depiction. A picture is much simpler to understand than a mere report of the regression coefficient for an interaction. A researcher can plot the effect in a graph by calculating the predicted values at contrasting levels of the independent variable and the moderator. The term slopes test sometimes is used to refer to the comparison of slopes in interpreting an interaction's effect.
