If there are two unbiased estimators of a parameter,the one whose variance is smaller is said to be relatively efficient.

Question

Quizplus · Accepted Answer

A relatively efficient estimator is the one with the smaller variance. This means that it is more likely to be closer to the true value of the parameter than the other estimator, making it a better choice for estimation. An unbiased estimator with a smaller variance is always relatively efficient compared to other unbiased estimators of the same parameter.
