Error Sources(cont) I did a scale factor calibration by driving 28 miles. according to mileage markers on Interstate 95. and in both directions i recorded 27. 425 miles on my odometer Thus the scale factor is 27425 odometer indicted miles SF 980 28 actual miles And any error in the scale factor due to readout resolution is 025 SE ×9 ±0006Error Sources (cont.) • I did a scale factor calibration by driving 28 miles, according to mileage markers on Interstate 95, and in both directions I recorded 27.425 miles on my odometer • Thus, the scale factor is 27.425 odometer indicted miles S.F. = = .980 28 actual miles • And any error in the scale factor due to readout resolution is .025 e ≅ ±.0006 SF = ± 28⋅ 2
