Non numeric categorical data examples
OneHotEncoder: as you already read before, one-hot encoding maps a categorical feature, represented as a label index, to a binary vector with at most a single one-value indicating the presence of a specific feature value from among the set of all feature values. Some examples include: name, hair colour, qualification etc. Below 21 years 21 to 35 years 36 to 58 years 59 years and above This is an example of ordinal data collection.

For example, when studying the severity of the bug in the software, severity is a categorical variable with ordered categories which are; critical, medium and low. Then pass that column to the OneHotEncoder class.
The first thing to do when you start learning statistics is get acquainted with the data types that are used, such as numerical and categorical variables. Different.
