Sequential Sampling in Attributes Sampling

What is sequential sampling in attributes sampling?

Choose the correct statement:

A. Sequential sampling is primarily used in nonstatistical sampling.

B. Sequential sampling allows for a fixed sample size.

C. Sequential sampling may result in early termination of sampling.

D. Sequential sampling is more cost-effective than nonsequential sampling.

Answer:

Sequential sampling in attributes sampling allows for a flexible sample size and can potentially lead to earlier termination of the sampling process if the gathered data fulfills the research needs.

In attributes sampling, sequential sampling involves an ongoing assessment where the sample size determination is not fixed and can adapt based on the information collected. This dynamic approach enables researchers to make decisions regarding the continuation or completion of the sampling process earlier than planned if sufficient data has been obtained to draw conclusions.

The statement that best describes sequential sampling in attributes sampling is that it may result in early termination of sampling. This feature distinguishes it from nonstatistical sampling methods, where sample sizes are predetermined and fixed, such as convenience sampling.

While sequential sampling offers the advantage of flexibility and potential efficiency gains through early termination, it does not automatically guarantee cost-effectiveness over nonsequential sampling in all situations. The decision to use sequential sampling should be based on the specific research goals, available resources, and the nature of the data being collected.
