What are five advantages of work sampling over time-study methods?

What will be an ideal response?

1. Because a single observer can observe several workers simultaneously, it is less expensive. 2. Observers usually do not require much training, and no timing devices are needed. 3 . The study can be temporarily delayed at any time with little impact on the results. 4. Because work sampling uses instantaneous observations over a long period, the worker has little chance of affecting the study's outcome. 5. The procedure is less intrusive and therefore less likely to generate objections.
