Q
Q: If the true value of a quantity is 100 and the measured value is 98, what is the percentage error?
Solution:
Percentage error = (|True value - Measured value| / True value) * 100 = (|100 - 98| / 100) * 100 = 2%.
Steps: 8
Show Steps
Step 1: Identify the true value, which is 100.
Step 2: Identify the measured value, which is 98.
Step 3: Calculate the difference between the true value and the measured value: |100 - 98|.
Step 4: The difference is 2.
Step 5: Divide the difference by the true value: 2 / 100.
Step 6: The result of the division is 0.02.
Step 7: Multiply the result by 100 to convert it to a percentage: 0.02 * 100.
Step 8: The final result is 2%, which is the percentage error.
