Bias - GCSE Maths Definition

In the context of GCSE Maths, 'bias' refers to a systematic error that leads to a distortion in data or results, making them unrepresentative of the population being studied. Bias can occur in data collection methods, sample selection, or through leading survey questions, and it can impact the accuracy and validity of statistical conclusions. Identifying and minimising bias is crucial when designing surveys or experiments to ensure that the findings are fair and reflective of the true characteristics being measured. Recognising bias helps students make critical evaluations of data and understand the importance of objective information gathering.
