Consistency of an estimator can be checked by comparing____________?
Correct answer: D. Variance
- A. Standard Deviation
- B. Mean
- C. mean Square Error
- D. Variance
Explanation
Consistency is commonly examined through the estimator's variance as the sample size increases: a consistent estimator should have variance tending to zero, together with vanishing bias. Mean square error is also useful for overall estimator quality, but variance is the expected criterion in this question.
