Precision refers to the spread, or range, of data values obtained when some parameter is measured many times or in many patients.A small precision means that little variation exists in the data values.Then, the mean (or average) of the n values of the parameters x is defined by the symbol: 11ea6816_3f28_a94f_b611_375fa293fb7e_TB6242_11 The symbol F1F1F1S1F1F1F10x means the sum of all the measurements of x.
