Question

The variance of an estimator measures;

A. how close repeated values of the mean of the estimator are to each other.
B. how close the mean of the estimator is to the true value.
C. how close repeated values of the estimator are to each other.
D. how close the estimator is to the true value.

Answer 1

B. how close the mean of the estimator is to the true value.

Step-by-step explanation:

The variance is used to calculate or to give rather a more accurate estimation of how close the mean of the estimator to the true value, this can help to know the true real beheavior of the population towards the event that we are estimating and how it would affect our predictions.
