Efficiency of Estimators
An estimator is a simple statistic that represents the population properties. A specific property can be represented by using many different estimators.
When you're selecting an estimator, you need to consider its efficiency and compare it with all the other alternatives.
When you're looking for the most efficient estimator, you're basically looking for the one that shows you the lowest expected variance of the error. This means that the most efficient estimator is the best possible approach to the population you're studying.
