B) The time-study method is usually used for less-repetitive work with no definite work cycle.

Question

Quizplus · Accepted Answer

Work-sampling is a statistical method that involves taking random observations of a worker's activity, and it requires many observations to be reliable. Option A is incorrect because historical and snap-back are not the two methods of using a stopwatch in time studies; the two methods are continuous and snap-back. Option B is incorrect because time studies are often used for work with a definite work cycle, and option C is incorrect because an RF greater than 1 means the worker is faster than a standard worker, not slower.
