Below are sample questions representative of the exercises included on this worksheet and related 7.12 Measurement Error and Uncertainty skill assessments:

Problem 1Difficulty: Mastery

What is the best conclusion?

AClass 1 is definitely longer because it was measured first.

BClass 2 is definitely longer because 19.0 is bigger.

CThe overlap proves the hallway has two different lengths.

DYou cannot claim a clear difference because the uncertainty ranges overlap.

Solution & Explanation:Class 1 range: 18.3–18.9. Class 2 range: 18.7–19.3. Because these overlap (18.7–18.9), both results could represent the same true length.

Problem 2Difficulty: Mastery

Which statement about percent uncertainty is correct?,A. A has the larger percent uncertainty. | B. They have the same percent uncertainty. | C. B has the larger percent uncertainty. | D. Percent uncertainty depends only on the units

Anot the numbers.,A,Percent uncertainty A: 0.02/0.50 = 0.04 = 4%. Percent uncertainty B: 0.1/4.0 = 0.025 = 2.5%. So A has the larger percent uncertainty.,NO,,,,,online_practice_skill_page,practice,Measurement Error and Uncertainty practice questions for Grade 7 science,Grade 7 science measurement error and uncertainty online practice

Problem 3Difficulty: Mastery

What best describes what is happening?

ANo error because repeating trials removes systematic error.

BLow precision but high accuracy due to random error.

CHigh precision but low accuracy due to a systematic error.

DHigh accuracy because the values cluster closely.

Solution & Explanation:Tight clustering means high precision. A consistent offset from the reference indicates systematic error, which reduces accuracy even if the data are precise.
