Bias is related to consistency in that consistent estimators are convergent and asymptotically unbiased hence converge to the correct value as the number of data points grows arbitrarily largethough individual estimators in a consistent sequence may be biased so long as the bias converges to zero ; see bias versus consistency.
All else being equal, an unbiased estimator is preferable to a biased estimator, but in practice all else is not equal, and biased estimators are frequently used, generally with small bias. When a biased estimator is used, bounds of the bias are calculated. A biased estimator may be used for various reasons: Further, mean-unbiasedness is not preserved under non-linear transformations, though median-unbiasedness is see effect of transformations ; for example, the sample variance is an unbiased estimator for the population variance, but its square root, the sample standard deviationis a biased estimator for the population standard deviation.
