What does Unbiasedness mean in statistics?
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. For example, the OLS estimator bk is unbiased if the mean of the sampling distribution of bk is equal to βk.
What is example of unbiased?

Is being unbiased considered a bias?
An estimator or decision rule with zero bias is called unbiased. In statistics, “bias” is an objective property of an estimator. Bias can also be measured with respect to the median, rather than the mean (expected value), in which case one distinguishes median -unbiased from the usual mean -unbiasedness property.
