Which type of error arises from limitations in the human senses of sight, touch, and hearing?
Personal errors
Which of the following is NOT a source of natural errors in surveying?
Improperly adjusted instruments
What type of error is caused by imperfections in the construction or manufacture of surveying instruments?
Instrumental errors
What does the term "precision" refer to in the context of surveying measurements?
The degree of refinement and consistency with which a physical measurement is made
What is the main characteristic of systematic errors in measurements?
They always have the same sign and magnitude under constant conditions.
Which of the following is NOT a source of systematic errors in surveying?
Failure of a tapeman to exert the correct amount of pull on the tape ends
What distinguishes mistakes from errors in measurements?
Mistakes are not classified as errors and are caused by human factors.
Which type of error is also known as cumulative error?
Systematic Errors
What causes accidental errors in surveying measurements?
Changes in field conditions.
Why are mistakes and blunders not classified as errors in measurements?
They are usually so large in magnitude when compared to errors.
How can systematic errors be mitigated in surveying measurements?
By employing proper techniques with surveying instruments.
Which of the following is NOT a type of measurement?
Trigonometric measurements
Which of the following is an example of an accidental error?
All of the above
Which of the following is NOT a source of instrumental errors?
Incorrect reading of the instrument
Systematic errors are caused by:
Known sources that affect the measurements in a consistent manner
Which of the following is NOT a way to minimize errors in surveying measurements?
Ignoring small errors that are within acceptable limits
The most probable error in a set of measurements is calculated using:
The standard deviation of the measurements
Learn about accidental errors in surveying measurements that are beyond the surveyor's control and persist even after eliminating mistakes and systematic errors. Explore examples such as incorrect application of force on tape ends during measurement.
