USE_REP_AVERAGE_FOR_PERCENT_DIFFERENCE

BOOLEAN

When the system is performing a precision assessment and calculating Percentage Difference, then:

  • If checked (default on deploy), then the calculation is:
    Xbar = (duplicate/replicate sample scheme analyte's Numeric Final Value + original sample scheme analyte's Numeric Final Value)/2
    Percentage Difference = Absolute Value (duplicate/replicate sample scheme analyte's Numeric Final Value—Xbar) x 100 / Xbar
  • Otherwise if cleared (default if missing), then the %calculation is:
    Xbar = (duplicate/replicate sample scheme analyte's Numeric Final Value + original sample scheme analyte's Numeric Final Value)/2
    Percentage Difference = Absolute Value (duplicate/replicate sample scheme analyte's Numeric Final Value—original sample scheme analyte's Numeric Final Value) x 100 / Xbar

Typically the preference is not set at role or user level.
