Three measurements of 34.5 m, 38.4 m, and 35.3 m are taken. If the accepted value of the measurement is 36.7 m, what is the percent error for each measurement?

Answer :

Final answer:

The respective percent errors for the measurements 34.5 m, 38.4 m, and 35.3 m compared to an accepted value of 36.7 m are calculated to be 5.99%, 4.63%, and 3.81%.

Explanation:

The percent error for a measurement can be calculated by taking the absolute value of the difference between the accepted value and the measured value, dividing by the accepted value, and then multiplying by 100% to convert to a percentage. The formula is as follows:

Percent Error = |(Measured Value - Accepted Value)| / Accepted Value * 100%

Using this formula, we can calculate the percent error for each of your measurements:

  1. Measurement 1 (34.5 m): Percent Error = |(34.5 m - 36.7 m)| / 36.7 m * 100% = 5.99%
  2. Measurement 2 (38.4 m): Percent Error = |(38.4 m - 36.7 m)| / 36.7 m * 100% = 4.63%
  3. Measurement 3 (35.3 m): Percent Error = |(35.3 m - 36.7 m)| / 36.7 m * 100% = 3.81%

This means that your measurements were off by 5.99%, 4.63%, and 3.81% respectively.
