When should percent error be used?
When you compare two accepted values of the same quantity.
When you compare two experimental values of the same quantity.
When you compare an accepted value to an experimental one.
We should never use percent error.
Solution
Solution Steps
Step 1: Understand the Question
The question asks about the appropriate scenario for using percent error. Percent error is a measure used to express the difference between an experimental value and an accepted or true value.
Step 2: Analyze Each Option
Option 1: "When you compare two accepted values of the same quantity."
This is incorrect because percent error is not used to compare two accepted values; it is used to compare an experimental value to an accepted value.
Option 2: "When you compare two experimental values of the same quantity."
This is incorrect because percent error is not used to compare two experimental values; it is used to compare an experimental value to an accepted value.
Option 3: "When you compare an accepted value to an experimental one."
This is correct because percent error quantifies the difference between an experimental value and an accepted value.
Option 4: "We should never use percent error."
This is incorrect because percent error is a useful measure in many scientific and engineering contexts.
Final Answer
\(\boxed{\text{When you compare an accepted value to an experimental one.}}\)
