In time study terminology, the average time recorded across observed cycles (before applying performance rating) is called the ________.

Difficulty: Easy

Correct Answer: Representative (average observed) time

Explanation:


Introduction / Context:
Understanding the ladder from observed time to standard time is essential: observed → representative → normal → standard. Each step formalises adjustments for performance and allowances.



Given Data / Assumptions:

  • Multiple cycle observations are timed.
  • Performance rating and allowance systems are available.
  • Stable method and conditions.


Concept / Approach:
Representative time is the mean (or statistically suitable average) of observed times after eliminating abnormal values. Normal time = representative time * rating factor. Standard time = normal time + allowances.



Step-by-Step Solution:

Collect observed times → compute average → representative time.Apply rating → obtain normal time.Add allowances → obtain standard time.


Verification / Alternative check:
Time study manuals explicitly define these terms in the same sequence.



Why Other Options Are Wrong:
Standard/Normal are later-stage results; allowance time is only a component.“Rated time” is ambiguous and not the standard terminology here.



Common Pitfalls:
Confusing “normal” with “observed”; failing to filter outliers before averaging.



Final Answer:

Representative (average observed) time
