If the true value of a measurement is 50.0 units and the measured value is 48.0 units, what is the percentage error?
Steps
Concepts
Step 1: Identify the true value and the measured value. The true value is 50.0 units and the measured value is 48.0 units.
Step 2: Subtract the measured value from the true value. Calculate 50.0 - 48.0.
Step 3: Take the absolute value of the result from Step 2. This means ignoring any negative sign.
Step 4: Divide the absolute difference (from Step 3) by the true value (50.0).
Step 5: Multiply the result from Step 4 by 100 to convert it into a percentage.
Step 6: The final result is the percentage error.
