It is desired to determine the most probable value of an angle which has been measured at different times by different observers with equal care. The values observed were as follows: 74deg 39min 45sec (in 2 measurements), 74deg 39min 27sec (in four measurements), and 74deg 39min 35sec (in 6 measurements)
