Question
A student measures a sample's weight as 18.3g, but the true weight is 20.0g. What is the absolute error?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Absolute error is calculated as measured value - true value. So, 18.3g - 20.0g = -1.7g. The negative sign indicates the measurement is lower than the true value.
Hint
Subtract the true value from the measured value.
