The independent variables $x _ { 1 }$ and $x _ { 2 }$ interact when the effect on $E ( y )$ of a change in $x _ { 1 }$ depends on $x _ { 2 }$.

Question

Quizplus · Accepted Answer

Interaction between independent variables occurs when the effect of one variable on the dependent variable is different at different levels of another variable, meaning the impact of $x_1$ on $E(y)$ changes depending on the value of $x_2$.
