Create dummy variables from one
Create dummy variables from one categorical variable in SPSS. This technique is used in preparation for multiple linear regression when you have a categorical variable with more than two groups which you want to use as an independent variable.
For example, say I wanted to use a participants Ethnicity and there were 5 different ethnic groups. This variable is nominal and has 5 groups so I cannot use it as it is for linear regression. I would need to create 4 dummy variables.
I do not explain the theory of creating dummy variables in this video. For that, please see a good stats textbook.
