Question 1
How is the statistical tool of adequate sample sizing used in work measurement?Question 2
What are predetermined time standards?Answer 1
The two applications are in time studies and in work sampling. Both determine how many measurements need to be taken before specified levels of accuracy and confidence are achieved. This prevents users of time studies and work sampling from drawing faulty conclusions from too-small samples.Answer 2
Predetermined time standards divide manual work into small basic elements that already have established times.
