What is bias in data analytics?

Bias in data analytics is a systematic error that skews results. It happens when data, methods, or interpretations consistently push findings in a particular direction, rather than just showing random variation. This means the conclusions you draw may be off from the true value in a predictable way, which can mislead decisions. For example, using a dataset that doesn’t represent the population, or using measurement tools that favor a certain outcome, introduces bias that distorts estimates. In contrast, random fluctuations are random noise that tends to even out with more data, so they don’t create a consistent direction of error. A result that’s always correct would sidestep bias entirely, and a measurement that never affects conclusions implies no influence on the outcome, which again isn’t bias.
