terrance.who.intQuantitative QC Module 7 Annex 3 Calculate the Ranges The mean of these data is 190.5, and the SD is 2. To calculate the acceptable ranges for use in quality control decisions: 1. Range for 1 SD: Subtract the SD from the mean (190.5 – 2 = 188.5) Add the SD to the mean (190.5 + 2 = 192.5) Range for 1 SD is 188.5 - 192.5 . 2.

extranet.who.intQuantitative tests measure the quantity of a substance in a sample, yielding a numeric result. For example, the quantitative test for blood glucose can give a result of 5 mg/dL. Since quantitative tests have numeric values, statistical tests can be applied to the results of QC material to differentiate between test runs that
