I performed a solar observation the other day with 12 observations, 6 direct, 6 reverse. The results of those observations are as follows:
My question is this; what is the standard deviation of that set and is standard deviation the same thing as standard error when applied to this scenario?
I don't have a strong background in statistics, but I'm trying to learn. I really want to start applying Least Squares analysis to my work.
For the record, I came up with a standard deviation of 3.3". The observations were made with a Topcon GTS 302 instrument, backsighting a prism on a tripod and tribrach that were in good adjustment at a distance of 583.80 feet. The DIN specs on that instrument list it as having an angular accuracy of 3". The observations were Trailing edge method.
I realize that by following certain guidelines posted here once before that I can test the angular accuracy of my instrument and come up with real world accuracies, provided I come to grips with statistics, hence, I need to know that what I'm doing when it comes to computing standard error is correct.
Thanks for the help.
