A reseаrcher wаnts tо mоdel the аmоunt of damage (Damage) in a car accident using a multiple linear regression model: Damage = β0 + β1 * Speed + β2 * Cell + β3 * (Speed × Cell) The independent variables are Speed (the speed of the car at the time of the accident) and Cell (whether the driver of the car was talking on a cell phone at the time of the accident). Cell is a dummy variable with two categories (yes=1 and no=0). The interaction term (Speed × Cell) is included in the regression model because it is believed that the impact of Speed on Damage varies with the value of Cell.
