Question

Which of the following is a characteristic of a systematic error?
  1. A

  2. B
    It causes readings to scatter randomly on both sides
  3. C
    It can be reduced by averaging many readings

Correct answer

It shifts all readings by the same amount in one direction

Systematic errors are consistent and unidirectional; averaging does not eliminate them. Random errors scatter and can be reduced by averaging.
