A surveying instructor sent all the 40 students in his class out to measure a distance between two points marked ona runway. The students working in groups of four came up with 10 different measurements as follows: 922.11, 921.24, 921.86, 920.99, 922.59, 922.15, 922.33, 922.11, 920.22, and 920.01meters. Assuming these values are equally reliable and that variations result only from accidental errors, determine the relative precision of a single measurement and the relative precision of the mean

Errors in surveying

An error in surveying is defined as the difference between two or more values of an identical quantity. However, the estimates are never accurate and there will always be a degree of variability regardless of the research tool or method used. These differences are known as errors that need to be reduced or eliminated to maintain certain levels of accuracy. Even if you carefully follow the prescribed test procedures, the considerations may contain errors.
