Systematic errors: A systematic error is an error that, under the same conditions, will always be of the same shape and size.

A systematic error always follows some definite mathematical or physical law and a correction can be determined and applied.
Such errors are of constant character and are regarded as positive or negative according to as they make the result too great or too small.
Blunders: A blunder (or gross error) is a significant, unpredictable mistake caused by human error that often leads to large discrepancies.
Blunders are typically the result of carelessness, miscommunication, fatigue, or poor judgment. Examples of common blunders are:
i) Improperly leveling of the surveying instrument.
ii) Setting up the instrument or target over the wrong control point.
Random (or accidental) errors are not directly related to the conditions or circumstances of the observation.
For a single measurement or a series of measurements, the error remains after all possible systematic errors and blunders have been eliminated.
Random errors are unpredictable and are often caused by factors beyond the control of the surveyor. Their occurrence, magnitude, and direction (positive or negative) cannot be predicted.

Random errors
Random errors are unpredictable and occur by chance. They can happen due to various factors such as human error, equipment malfunction, or environmental conditions. In the given scenario, the error made by the surveyor falls under the category of random errors.
Explanation:
- Surveyor's error: The surveyor made an error during the survey of a project. This error is associated with his skills and vigilance, indicating that it was not intentional but rather a mistake made by chance.
- Unpredictable: Random errors are unpredictable and can occur without any specific pattern or trend. They can happen due to various factors that are difficult to control or eliminate.
- Factors contributing to random errors: Random errors can be caused by factors such as human error, equipment limitations, environmental conditions, or even external disturbances. These factors can introduce variability in the measurements or observations made by the surveyor.
- Lack of consistency: Random errors do not have a consistent direction or magnitude. They can cause measurements to be either higher or lower than the true value without any specific pattern.
- Statistical analysis: Random errors can be minimized through statistical analysis techniques. By taking multiple measurements and calculating the average, the random errors tend to cancel each other out, resulting in a more accurate estimate of the true value.
- Improvement through training and quality control: Random errors can also be reduced by improving the skills and vigilance of the surveyor through proper training. Implementing quality control measures, such as regular calibration of equipment and double-checking measurements, can also help in minimizing random errors.
Therefore, based on the given scenario, the type of error committed by the surveyor is a random error, as it was an unintentional mistake associated with chance factors rather than a consistent or systematic error.
