👉 In statistics, a "unpaised" or "biased" estimate is an estimate that is not influenced by any particular value in the data set being estimated. This means that if we assume the true value of a parameter to be 0, then the estimate will also be 0. For example, consider an estimator for the mean of a normal distribution with unknown variance: $$ \hat{\mu}_n = \frac{1}{\sqrt{n}} \sum_{i=1
