Question:

(i) Caused by observer’s misunderstanding and carelessness
(ii) Reading an angle counter-clockwise, but recording it as clockwise angle
(iii) Sighting the wrong target
(iv) Poor judgment by the observer

Show Hint
A mistake is a one-time error caused by human misunderstanding or carelessness, whereas errors like cumulative or probable errors occur due to systematic or random factors.

- Accidental error
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The error described involves misunderstanding, carelessness, and misjudgment by the observer. These characteristics align with a mistake, which is a one-time error caused by human error, not a recurring or systematic issue like a cumulative or probable error.
Step 1: Understanding the Error Characteristics
Mistakes are typically due to a lack of attention or care, leading to a misinterpretation of readings or actions. The given options like cumulative errors and probable errors refer to different types of systematic or random errors, which are not caused by the observer's misunderstanding and carelessness.
Step 2: Conclusion
Therefore, the correct answer is (A) Mistake.
