Each student aligns the edge of the object with the left edge of the ruler as shown above. all four students read the ruler with a measurement of 4.6 cm. which statement describes the data they collect? a. the data have high precision but poor accuracy because of a systematic error. b. the data have high precision but poor accuracy because of a random error. c. the data have poor precision and poor accuracy because of a systematic error. d. the data have poor precision and poor accuracy because of a random error.

The data have high precision but poor accuracy because of a systematic error.

Explanation:

Each student aligns the edge of the object with the left edge of the ruler as shown above. All four students read the ruler with a measurement of 4.6 cm. Which statement describes the data they collect?a. The data have high precision but poor accuracy because of a systematic error. b. The data have high precision but poor accuracy because of a random error. c. The data have poor precision and poor accuracy because of a systematic error. d. The data have poor precision and poor accuracy because of a random error.

Accuracy is how close a value is to its true value. An example is how close an arrow gets to the bull's-eye center. Precision is how repeatable a measurement is.

systematic error has to deal with consistent repeatable errors, owning to faulty measuring equipment
