Question

distinguish between accuracy and precision. give an example of a measurement that is precise but inaccurate and another example of a measurement that is accurate but imprecise. choose the correct answer below. a. a measurement that is precise but inaccurate is a baby weighing 66 pounds 2 ounces. a measurement that is accurate but imprecise is a football field being 330 feet and 4 inches long. b. a measurement that is precise but inaccurate is a garbage truck weighing 1 ton. a measurement that is accurate but imprecise is a professional basketball player being 4 feet 3 inches tall. c. a measurement that is precise but inaccurate is a bowling ball weighing 2 pounds. a measurement that is accurate but imprecise is a couch being 6 feet long. d. a measurement that is precise but inaccurate is a laptop that weighs 11.26 tons. a measurement that is accurate but imprecise is a piece of paper being 1 foot long.

Explanation:

Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close repeated measurements are to each other. A precise - but - inaccurate measurement has a high level of detail but is far from the true value. An accurate - but - imprecise measurement is close to the true value but lacks detail. A laptop weighing 11.26 tons is highly precise (due to the two - decimal - place measurement) but extremely inaccurate as laptops do not weigh that much. A piece of paper being 1 foot long is a general estimate (imprecise) but could be close to the actual length (accurate).

Answer:

C. A measurement that is precise but inaccurate is a laptop that weighs 11.26 tons. A measurement that is accurate but imprecise is a piece of paper being 1 foot long.
