Explanation:

Data bias is a systematic error in data collection, processing, or analysis that shifts results away from accurate, objective outcomes. It reduces data accuracy, does not skew data toward a "right" outcome, and does not simplify sharing results. The correct description is that it is an error causing systematic directional skew of results.

Answer:

It is an error that can systematically skew results in a certain direction.
