   What is Dummy coding in Python?

   • In this section of the dummy coding in Python tutorial, we are going to work with the variable “rank”. That is, we will create dummy variables in Python from a categorical variable with three levels (or 3 factor levels). In the first dummy variable example below, we are working with Pandas get_dummies () the same way as we did in the first example.

   What is Dummy coding in statistics?

   • In these steps, categorical variables in the data set are recoded into a set of separate binary variables (dummy variables). Furthermore, this re-coding is called “dummy coding” and involves the creation of a table called contrast matrix. Statistical software, such as R, SPSS, or Python, can automatically do dummy coding.
