How to handle Nominal Data

Question

I have data which has colours as a column how should I handle such kind of data to do predictive modelling?

Answer 1

Nominal data is basically data which can be neither ordered nor measured it's merely different categories, for example, color - all are similar they don't have any hierarchical order. 

There are many ways to deal with nominal data for predictive modeling - which approach to choose is based on the scenario and the kind of predictive modeling/visualization you would like to do.
