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.

6. A line was measured 5 times with a tape on a windy day with these results: 286.85, 286.96, 286.77, 286.80, and 286.88 ft. Find the mean and standard deviation of a single measurement. Then, the measurement was repeated 15 more times, giving a mean of 286.87 ft and a standard deviation of 0.06 ft. Have there been enough repetitions to assure that the standard error of the mean is less than 0.02 ft?
11. As part of a project, you have been asked to determine the adjusted height of a client's office building. To obtain sufficient redundancy in the number of observations required to perform the necessary least-squares solution, you have measured 2 distances (d. and d.) and 2 angles (0, and 0.) as depicted in the following figure. The subsequent observations and their associated uncertainties are summarized in the table below. Assume that all observations were obtained independently and that 0, is exactly 69° 18' 33".

A surveying instructor sent out six groups of students to measure a distance between two points marked on the ground. The students came up with the following six different values: 250.25, 250.15, 249.90, 251.04, 250.50, and 251.22 meters. Assuming these values are equally reliable and that variations result from accidental errors, determine the (a) most probable value of the distance measured, (b) probable error of a single measurement and (c) probable error of the mean
