An observer notes the reading of scale from different angles (parallax) while measuring the length of the wire, what type of error is possible:
Correct answer: D. Random Error
- A. Systematic error
- B. Zero error
- C. Precise error
- D. Random Error
Explanation
Parallax error is due to the positioning of the eye while recording a value. The positioning and the error in the reading birthed from this positioning is completely random since the inaccurate reading could be either greater or lesser than the true value.
