Exercise

Generalizing into ranges

K-anonymity can be a good privacy model for specific datasets that don't have many dimensions. The two main anonymization techniques used to transform a dataset into a k-anonymous table are generalization and suppression.

In this exercise, you will transform a satisfaction rating dataset to a 3-anonymous table containing possible sensitive attributes like satisfaction_rate and work_hours. Some combinations appear less than three times. Fix that to make the DataFrame 3-anonymous.

The DataFrame is available as employees. A k value of 3 is also available.
