问题如下:

Perkiomen Kinzua, a seasoned auditor, is auditing last year’s transactions for Conemaugh Corporation. Unfortunately, Conemaugh had a very large number of transactions last year, and Kinzua is under a time constraint to finish the audit. He decides to audit only the small subset of the transaction population that is of interest and to use sampling to create that subset. The most appropriate sampling method for Kinzua to use is:

选项:

A.judgmental sampling

B.systematic sampling

C.convenience sampling

解释:

With judgmental sampling, Kinzua will use his knowledge and professional judgment as a seasoned auditor to select transactions of interest from the population. This approach will allow Kinzua to create a sample that is representative of the population and that will provide sufficient audit coverage. Judgmental sampling is useful in cases that have a time constraint or in which the specialty of researchers is critical to select a more representative sample than by using other probability or non-probability sampling methods. Judgement sampling, however, entails the risk that Kinzua is biased in his selections, leading to skewed results that are not representative of the whole population.

嗨,从没放弃的小努力你好:


B选项为每隔k个样本抽一个;

C选项为根据样本的可获得性,抽最方便获取的样本。

这两个选项和本题毫无关系。本题的描述就是直指judgmental sampling的,没有B、C的可能。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
