Question：
In generating an estimate of a population parameter, a larger sample size is most likely to improve the estimator's:
A. consistency.
B. efficiency.
C. unbiasedness.
Answer = A
A consistent estimator is one for which the probability of estimates close to the value of the population parameter increases as the sample size increases. Unbiasedness and efficiency are properties of an estimator's sampling distribution that hold for any size sample.
