Nominal data is categorized data with no order/hierarchy or rank among the categories, example cricket balls can be categorized into n number of categories based on color, without defining any hierarchy or rank among them.

To deal with nominal data make your nominal data column as a factor, so that the machine recognizes the same just as a factor.

Nominal Data:
Nominal values represent discrete units and are used to label variables, that have no quantitative value. Just think of them as „labels“. Note that nominal data that has no order. Therefore if you would change the order of its values, the meaning would not change. You can see two examples of nominal features below:

The left feature that describes a persons gender would be called „dichotomous“, which is a type of nominal scales that contains only two categories.
