You measure an angle with a theodolite several times and record the following observations:
114° 27’ 49”
114° 27’ 37”
114° 27’ 39”
114° 27’ 41”
114° 27’ 43”
114° 27’ 44”
What is your best estimate of the true value of the angle? Give your answer to 1 decimal place of a second.
What is the standard error of the observations? Give your answer to 1 decimal place of a second.
