A Simplified Calculation of the Real Confidence Interval in Analytical Methods
Galban, Javier
Journal of Chemical Education, v81 n7 p1053 Jul 2004
A simplified mathematical model for the calculation of imprecision associated with the construction of a calibration line is presented. The model also aims at a discussion on variables that really affect it and to integrate the resulting imprecision with that caused by the other steps in the analytical method in order to calculate a real confidence interval for an analytical determination.
