For example, the political affiliation example that codes Democrat as a “1,” Republican as a “2” and Independent as a “3” could be recoded into the dichotomous variable Republican, with all “2s” recoded as “1” and other values coded as zero.Click “ Continue” after entering the old and new values for your dummy codes, then click “ OK.” SPSS will then recode the categorical variable as you have specified. Under “New Value,” type a “1,” then click “Add.” On the “Old Value” side, select the “All Other Values” button and type “0” as the new value. Under “Old Value,” enter the category value to be recoded.

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.

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: With some guidance, you can craft a data platform that is right for your organization’s needs and gets the most return from your data capital.
