单选题

In generating an estimate of a population parameter, a larger sample size is most likely to improve the estimator's:

【正确答案】 B
【答案解析】

Identify and describe the desirable properties of an estimator (unbiased, efficient, consistent). Unbiasedness and efficiency are properties of an estimator's sampling distribution that hold for any size sample. A consistent estimator is one for which the probability of estimates close to the value of the population parameter increases as sample size increases.
