Use of the Statistics to Determine Relative Maximum Value Knowing one-sigma is about ~4uV/C, customer may assume the maximum offset drift to be: 12uV/C (3*sigma) where 1 out of 370 units will NOT meet this max spec 16uV/C (4*sigma) where 1 out of 15,787 units will NOT meet this max spec 20uV/C (5*sigma) where 1 out of 1,774,277 units will NOT meet this max spec 24uV/C (6*sigma) where 1 out of 506,797,345 units will NOT meet this max spec Estimating a value of standard deviation (sigma)
