This error is small and is equally liable to be plus or minus thus partly compensating in nature. The maximum permissible error in an observation is 3.29s (where s is the standard deviation of sample distribution) and is used to separate mistakes or blunders from the random errors. Ivo Silveira 8877, km. She also wishes to thank Ramesh PE of Tektronix for presenting her the problem.
Probable Error Formula The measurement of baseline has an important role in the triangulation surveying, because the accuracy of computation of sides of the triangle depends upon the accuracy of the measured The X chart is shown in Figure 1.
