Bias vs. Offset — What's the Difference?

Often due to underlying assumptions.

Adjustment to align with correct values.

Systematic deviation in data modeling.

Offset is added to sensor outputs to correct for known biases in the sensor's baseline measurement.

Bias in statistics is a systematic error that causes a deviation from the true parameter of interest.

Offset is crucial for ensuring that measurements start from an accurate reference point.

Common biases include selection bias, measurement bias, and reporting bias.

While offset shifts the baseline of a measurement, gain scales the amplitude of the output.

While difficult to eliminate entirely, bias can be significantly reduced with careful methodological and model adjustments.

The correct offset can typically be determined through calibration tests comparing device output against known standards.

Bias directly affects the accuracy of predictions or measurements, typically reducing it.

Bias is not necessarily negative in intention but refers to a deviation that needs awareness and correction.

Yes, software, especially that based on machine learning, can inherit bias from the data it was trained on.
