Below are sample questions representative of the exercises included on this worksheet and related 12.5 Accuracy, Precision, Error, and Percent Difference skill assessments:

Problem 1Difficulty: Mastery

Two methods agree with each other to within 0.5%, but both used the same miscalibrated timer. Which conclusion is best?

AThe methods must be accurate because their percent difference is small.

BThe accepted value should be replaced by the average of the methods.

CThe timer error is random because both methods used it.

DSmall percent difference between methods does not prove accuracy when both share the same systematic error.

Solution & Explanation:Agreement between methods shows consistency, but shared systematic error can make both methods agree with each other while still being inaccurate.

Problem 2Difficulty: Mastery

A group measures acceleration due to gravity as 9.72, 9.75, 9.73, and 9.74 m/s². The accepted value is 9.80 m/s². What is the percent error of the mean?

A0.26%

B1.32%

C0.66%

D6.6%

Solution & Explanation:The mean is 9.735 m/s². Percent error = |9.735 - 9.80| / 9.80 x 100% = about 0.66%.

Problem 3Difficulty: Mastery

A motion sensor is later found to multiply every distance by 1.10. Repeated readings are tightly grouped. Which conclusion is best?

AThe data must be accurate because the readings are tightly grouped.

BThe data may be precise, but distances are systematically 10% too high.

CThe error is random because it is expressed as a percent.

DThe percent error is zero after averaging.

Solution & Explanation:Tight grouping indicates precision. A 1.10 scale factor makes every distance 10% high, creating systematic inaccuracy.
