Click the “ Output Variable” name box and type a name for your new dichotomous variable.Select the variable you want to recode, and then click the arrow, which moves the variable name into the box labeled “ Numeric Variable.” This opens a window that displays the variables in your data set. Click the “ Transform” menu at the top of the SPSS data sheet, then select “ Recode Into Different Variable,” because you will transform the categorical variable into one or more dichotomous or dummy variables.A person with a zero in these categories would be counted as independent). A person who identifies as one of these would be coded a “1” in the data set. For example, a categorical variable on political affiliation with three categories - Democrat, Republican and Independent - would be dummy coded into two dichotomous variables, such as Democrat and Republican. (Note the number of categories, remembering that dummy coding transforms a variable with “n” categories into “n-1” categories. Select the categorical variable that you want to dummy code.Let’s walk through the steps! Dummy Coding Step by Step This process is known as “dummy coding.” IBM SPSS makes dummy coding an unpretentious practice. An example would be employed and unemployed. These steps involve coding a categorical variable into multiple dichotomous variables, in which variables take the value of “1” or zero.įor clarity, a dichotomous variable is defined as a variable that splits or groups data into 2 distinct categories. Including these variables in an analytical model requires special steps to ensure the results can be interpreted properly. Statistical Analysis often include s variables in which the numbers represent qualitative categories (such as gender, ethnicity or political affiliation). If we consider a morning latte example, we might note the following:
