#### 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.
