A dummy independent variable is a variable that is scaled with a categorical 0-versus-1 coding scheme. It is used in regression analysis when the independent variable is qualitative or categorical in nature. A dummy variable takes on two values - 0 and 1 - depending on whether the condition is met or not. For example, in a study of the effect of gender on income, the researcher might use a dummy variable where male is coded as 1 and female as 0, or vice versa.
