What is Percent Error?

Back

Percent Error is a measure of how inaccurate a measurement is, expressed as a percentage of the actual value. It is calculated using the formula: Percent Error = |(Estimated Value - Actual Value)| / |Actual Value| * 100.

If the estimated value is 17,600 and the actual value is 21,300, what is the Percent Error?

Back

Percent Error = |(17,600 - 21,300)| / |21,300| * 100 = 17.4%.

If a student measures a length of 12 cm but the actual length is 14.25 cm, what is the Percent Error?

Back

Percent Error = |(12 - 14.25)| / |14.25| * 100 = 15.79%.

What does a low Percent Error indicate?

Back

A low Percent Error indicates that the estimated value is close to the actual value, suggesting high accuracy.

Front

What does a high Percent Error indicate?

Back

A high Percent Error indicates that the estimated value is far from the actual value, suggesting low accuracy.

Front

What is the difference between accuracy and precision?

Back

Accuracy refers to how close a measurement is to the actual value, while precision refers to how consistent repeated measurements are.

Front

What is an example of High Accuracy & High Precision?

Back

If multiple measurements of a length are taken and they are all very close to the actual length, this indicates high accuracy and high precision.
