Which of the following is not an accurate statement regarding experimental error?
A
Random errors can be completely eliminated with repeated measurements.
B
Systematic errors can be reduced by calibrating equipment.
C
Random errors affect the precision of measurements.
D
Systematic errors affect the accuracy of measurements.
Verified step by step guidance1
Understand the difference between random and systematic errors: Random errors are unpredictable variations that affect the precision of measurements, while systematic errors are consistent biases that affect the accuracy.
Recognize that random errors can be reduced by taking multiple measurements and averaging them, but they cannot be completely eliminated.
Identify that systematic errors can be minimized by calibrating equipment and using proper techniques, but they require correction to improve accuracy.
Evaluate each statement: Random errors cannot be completely eliminated, systematic errors can be reduced by calibration, random errors affect precision, and systematic errors affect accuracy.
Determine which statement is incorrect based on the understanding that random errors cannot be completely eliminated, making the statement about their complete elimination inaccurate.
