But Sam measures 0.62 seconds, which is an approximate value. |0.62 − 0.64| |0.64| × 100% = 0.02 0.64 × 100% = 3% (to nearest 1%) So Sam was only

The relative error expresses the "relative size of the error" of the measurement in relation to the measurement itself. Percent Error Worksheet Machines used in manufacturing often set tolerance intervals, or ranges in which product measurements will be tolerated or accepted before they are considered flawed.

The absolute error of the measurement shows how large the error actually is, while the relative error of the measurement shows how large the error is in relation to the correct

Probeer het later opnieuw. Repeat the same measure several times to get a good average value. 4. Step 2: Divide the error by the exact value (we get a decimal number) Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) As Percent Error Definition Chemistry Yes No Can you tell us more?
