In determining what makes a good estimator, there are two key features: The center of the sampling distribution for the estimate is the same as that of the population. When this property is true, the estimate is said to be unbiased.
WebbWhen deciding whether to reject the null hypothesis or not, we may commit one of two types of errors: Type I error - to reject the null hypothesis when it is true. The probability of committing Type I error is P(H 0 rejected H 0 is true) = α P ( H 0 rejected H 0 is true) = α.
