Bias of an estimator - Wikipedia

https://en.wikipedia.org/wiki/Bias_of_an_estimator

WEBAn estimator or decision rule with zero bias is called unbiased. In statistics, "bias" is an objective property of an estimator. Bias is a distinct concept from consistency: consistent estimators converge in probability to the true value of the parameter, but may be biased or unbiased; see bias versus consistency for more.

WEBUnbiasedness is a finite sample property that is not affected by increasing sample size. An estimate is unbiased if its expected value equals the true parameter value. This will be true for all sample sizes and is exact whereas consistency is asymptotic and only is approximately equal and not exact.

WEBIn statistics, estimators are usually adopted because of their statistical properties, most notably unbiasedness and efficiency. The statistical property of unbiasedness refers to whether the expected value of the sampling distribution of an estimator is equal to the unknown true value of the population parameter.

WEB5.4. Unbiased Estimators. Data scientists often use information in random samples to estimate unknown numercial quantities. For example, they might estimate the unknown average income in a large population by using incomes in a random sample drawn from the population. In this section we will examine one criterion for a good estimate.
