Quizplus · Accepted Answer

A dummy variable is not the same as an interaction variable. A dummy variable is a binary variable that takes on the values 0 or 1 to indicate the absence or presence of a particular categorical characteristic, while an interaction variable is created by multiplying two or more variables together to explore how their effects may interact or affect each other.
