WebUnsystematic variance is variability within individuals and/or groups of individuals. This variability is essentially random; some individuals change in one direction, others in an opposite direction, and some do not change at all.

WebA measurement system can be accurate but not precise, precise but not accurate, neither, or both. For example, if an experiment contains a systematic error, then increasing the sample size generally increases precision but does not improve accuracy. The result would be a consistent yet inaccurate string of results from the flawed experiment.
