In a stopwatch time study, the average time it takes a given worker to perform a task a certain number of times, without correction for performance rating or allowances, is the

A) average observed time.
B) standard time.
C) performance rating time.
D) normal time.
E) allowance time.

The average time it takes a worker to perform a task without any correction or adjustment is the average observed time in a stopwatch time study. This time serves as a baseline for further analysis and improvement. The other options (B, C, D, and E) usually require additional factors and considerations to determine the final time for the task, such as setting standards, adjusting for different skill levels or conditions, or adding allowances for rest or personal needs.
