Abstract: A simple and accurate regression equation was established to construct a regression curve that agreed with analytical requirements. This method uses new equations for the slope and y-intercept based on a new criterion, which is the sum of the absolute relative errors of the x-values (SARE). This paper derived new parameters SARE and AARE to determine the best linear relationship between the variables. The idea in this paper is that the best line fit for the points is that it has the smallest sum of the absolute relative error of the value of x. The SARE and AARE parameters can be used to find the best line and best dynamic range or working range to use in the experiments.
