Answer:
Random errors
Explanation:
In surveying, observation errors can be classified as systematic errors or random errors
Systematic errors are errors that have a non-zero average so that the effect of the error can also observed when we find the average of all the observed data values
Systematic error signifies an deficient model due to the bias in the average of the data obtained
Random errors are the errors remaining after the containing the systematic errors and slip ups. Hence random error are due to the limitations of environment including where the the measurements are made, hence the random error will be experienced to be approximately normal as the number of measurements are increased.
Therefore, random errors in surveying follows a normal distribution curve.
