- Abstract:
- Two linear fitting procedures are applied to internationally reference data in refractometry of solutions. Least square linear regression is compared to linear interpolation in the intervals of the two successive referenced data. The formulas and the validity of the procedures are shortly presented. The results are comparable, but for faster results, the linear regression method is preferred to the interpolation by intervals, albeit their bigger uncertainties values.
