I placed some cones on a sports playing field and estimated their locations using latitude/longitude coordinates. An example pair of estimated latitude/longitude coordinates is 54.96975, -1.51407.
On average, my estimated latitude was 0.00009 away from the actual latitude. On average, my estimated longitude was 0.0001 from the actual longitude.
Am I able to say, on average, what distance my estimated coordinates were from the actual coordinates?
