I want to know what calculation this report used for calculated Bias formula.
Gas-in-oil standard S =100 ppm, laboratory result for S = 90 ppm
Laboratory result for 4 duplicate sample = 250, 230, 210 and 240 ppm
laboratory result corrected for bias = 275, 254, 231, 263 ppm
How they get (The red bold) result from bias calculation.
I just know its tell ' calculate the bias of the laboratory by comparing its results for the gas-in-oil standard sample to what was actually prepared'
I calculate the bias factor [10/11] mean 250 multiply with [10/11] get 274.
So what formula its use..here I attached the paper for reference.
I hope you all helping me out. I already google and find the answer for a month.
