question 35

Multiple Choice

Including an interaction term between two independent variables, $X _ { 1 } \text { and } X _ { 2 } \text {, }$ allows for the following, except that:

• A) the interaction term lets the effect on Y of a change in \(X _ { 1 }\) depend on the value of \(X _ { 2 }\)
• B) the interaction term coefficient is the effect of a unit increase in \(X _ { 1 }\) and \(X _ { 2 }\) above and beyond the sum of the individual effects of a unit increase in the two variables alone.
• C) the interaction term coefficient is the effect of a unit increase in \(\sqrt { \left( X _ { 1 } \times X _ { 2 } \right) }\)
• D) the interaction term lets the effect on Y of a change in \(X _ { 2 }\) depend on the value of \(X _ { 1 }\)
