Which of the following statements regarding errors in measurement is incorrect?
Options
- ASystematic errors tend to be in one direction, either positive or negative.
- BSystematic errors can be estimated and the necessary corrections can be applied to the readings.
- CRandom errors occur irregularly and are unpredictable with respect to sign and size.
- DImperfection in experimental procedure or technique always leads to a random error.
Correct answer
D. Imperfection in experimental procedure or technique always leads to a random error.
Step-by-step solution
Systematic errors are those that tend to be in one direction, either positive or negative. Because their causes are known, they can often be estimated and necessary corrections can be applied to the readings.
Random errors occur irregularly and are unpredictable with respect to sign and size.
Imperfection in experimental procedure or technique (such as ignoring the buoyancy of air or measuring temperature under the armpit) is a known, consistent flaw that biases the result in a specific direction. Therefore, it is a source of systematic error, not a random error. The statement claiming it leads to a random error is incorrect.
Answer: Imperfection in experimental procedure or technique always leads to a random error.
