Binning

Binning converts the following:

• A continuous variable into a categorical variable.

• A continuous value into a continuous value. For example, age can be converted to 10 groups from 1 to 10.

• A categorical value with many values into a categorical variable with fewer variables.

For example, salary is a continuous variable. If you divide salary into 10 bins, you convert salary into a categorical variable with 10 values, where each value represents a salary range.

You can bin both numbers and character types VARCHAR2 and CHAR.
