The objective of this study is to present a simple method of statistical calculation that allowed us to determine the relationship between the different data obtained from the characterization of the synthetic carbonated apatites containing sodium, in order to find the fundamental substitution mechanism(s) for incorporation of Na⁺ and CO₃^2- and to establish the general formula. For that, a series of hydroxyapatites containing carbonate and sodium (Na-CO₃HAps) has been obtained by the precipitation method. All the compounds were characterized by infrared spectra (IR), powder X-ray diffraction (PXRD) and elemental analysis. The statistical treatment of the experiment result allows us to determine the relationship between one variable and the change in the other and to found the fundamental substitution mechanism(s) for incorporation of Na⁺ and CO₃^2- . Analysis of variance (ANOVA) allows us to test the models proposed.
