A table in a hospital database has a column for patient height in inches and a column for patient height in centimeters. This is an example of:

Dependent data refers to data whose values rely on other data, which is true here, but "redundant" more specifically describes the storage of the same information twice.

Duplicate data typically refers to identical records or entries, not different representations of the same underlying fact in different columns.

Invalid data implies that the data itself is incorrect or does not conform to expected rules, which is not necessarily the case here; the data might be correct, just stored redundantly.

Redundant data occurs when the same piece of information is stored multiple times in a database or can be derived from other existing data, such as height in inches and height in centimeters.
