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.

Question

The area of a triangular lot is to be computed, given the following trials for the
stadia interval factor: 102, 94, 97, 98, 104, and 107. The lot has its boundary named
as Station A, B, and C while the instrument is placed at the same Stations A, B, and
C.
At Station A reading the leveling rod at point B is at N15°E with a stadia intercept of
1.762, rod reading of 2.165 m, and an angle of -11°. At Sta. B rod reading at point C
is at N30°W with a stadia intercept of 1.729, rod reading of 0.722 m and an angle of
+14° and At Station C reading the leveling rod at point A has a stadia intercept of
1.248 rod reading of 1.657 m with 0°. Determine the area of the lot if the stadia
interval factor is the mean of the trials.
