Questions & Step-by-Step Solutions

If the true value of a measurement is 50 and the measured value is 48, what is the absolute error?
  • Step 1: Identify the true value of the measurement, which is 50.
  • Step 2: Identify the measured value, which is 48.
  • Step 3: Subtract the measured value from the true value: 50 - 48.
  • Step 4: Calculate the result of the subtraction, which is 2.
  • Step 5: The absolute error is the positive value of the result, so the absolute error is 2.
  • Absolute Error – The difference between the true value and the measured value, expressed as a non-negative number.
