What is the relative error of measurement? Relative error (RE)—when used as a measure of precision—is the ratio of the absolute error of a measurement to the measurement being taken. What is the corrected length of line BC using the compass rule? What is the corrected length of line BC using the transit rule?

The solutions and answers should have minimum of 3 decimals for linear measurements and should be in Degree-Minute-Seconds (2 decimals for seconds) for angular measurement, if not whole number. An engineer is tasked to measure a whole line multiple time. Since the length of the line is significantly longer than the steel tape, the engineer decided to measure the line in three segments. First, the engineer measures a 50m known line using the steel tape and find out that the tape is too long with the observation having only 49.2m. With these values, the correction factor of ???? = 50? − 49.2?. After determining such corrections for future calibration, the engineer measured each segments. The following are the observations: 1st Segment: 46.2m, 46.3m, 46.5m; 2nd Segment: 48.3m, 48.2m, 48.1m; 3rd Segment: 32.3m, 32.6m, 32.4m. Determine the complete expression of the most probable value (together with probable error) of the line.

2. The surveying professor require his student to measure line CD by pacing. In order for the student to provide an accurate length of line CD, he must know his pace factor. The student measured line AB , 45 meters long and walked through for several trials. The following numbers of steps or paces on line AB and CD are tabulated below. On line AB Trial Counted paces 1 72.50 2 72 71 4 72 71.5 On line CD Trial Counted paces 1 285 2 283 284.5 4 282 283.5 Determine the paced distance of line CD b. Determine the Relative Precision of а. measurement if the taped distance of line CD is 178.05 m. LO
The most probable value of several measurements of a line is 546.75 m. If 0.15 represents the probable error of the mean value, the changes are event that the true value Lies between 546.60 m and 546.90 m, as it is also probable that the true value lies outside of these limiting values O b. Lies between 546.75 m and 546.90 m, as it is also probable that the true value lies outside of these limiting values Oc. Is equal to 546.90 m Od. Is equal to 546.60 m
