Understand Percent Error: Understand the concept of percent error. Percent error is a measure of how inaccurate a measurement is, represented as a percentage of the actual value. The formula for percent error is: Percent Error = (|Measured Value - Actual Value| / Actual Value) × 100%Identify Values: Identify the measured value and the actual value. Measured Value = 19 inches Actual Value = 17.1 inchesCalculate Absolute Difference: Calculate the absolute difference between the measured value and the actual value. Absolute Difference = |Measured Value - Actual Value| Absolute Difference = |19 - 17.1| Absolute Difference = 1.9 inchesCalculate Percent Error: Calculate the percent error using the formula. Percent Error = (Absolute Difference / Actual Value) × 100% Percent Error = (1.9 / 17.1) × 100%Perform Division and Multiplication: Perform the division and multiplication to find the percent error. Percent Error = (1.9 / 17.1) × 100% Percent Error ≈ 0.1111 × 100% Percent Error ≈ 11.11%Round Percent Error: Round the percent error to the nearest tenth of a percent. Rounded Percent Error = 11.1%
