This work presents seven methods of curves adjustment, three of these, methods that use least squares regression techniques and the other four, using interpolation techniques. Initially, it brings some definitions that present to the reader all the mathematical foundation that rules the equations. In parallel, it seeks to discuss, through examples, the area of attribution of the described methods, realizing whenever possible a comparation between the several techniques presented and their errors in the estimates. In order to demonstrate that the techniques discussed here are feasible for use in basic education, it exposes an experience of applying one of these methods in solving a basic problem of the discipline of Physics. After presenting the step-by-step method of obtaining soil resistivity, a variable that is of the utmost importance for the elaboration of projects for grounding meshes that supply energy substations, We finish this work by solving the problem with the aid of adjustment techniques curves studied, proposing the inclusion of the methods addressed in one of the steps of the procedure to obtain soil resistivity. / Diante da necessidade de se discutir sobre métodos matemáticos capazes de ajustar curvas que representem dados experimentais.

Inicialmente, traremos algumas definições que apresentam ao leitor todo o embasamento matemático que rege os equacionamentos. Em paralelo, procuramos discutir, através de exemplos, a área de atribuição dos métodos descritos, realizando sempre que possível um comparativo entre as variadas técnicas apresentadas e seus erros nas estimativas.Com o intuito de demonstrar que as técnicas aqui discutidas são viáveis para utilização na educação básica, apresentaremos uma experiência de aplicação de um desses métodos na resolução de um problema básico da disciplina de Física. Após relatar os procedimentos do método de obtenção da resistividade do solo, que é uma variável de suma importância para a elaboração de projetos de malhas de aterramento que atendem subestações de energia. Finaliza-se este trabalho resolvendo o problema com auxílio das técnicas de ajustes de curva estudados, propondo a inclusão dos métodos abordados em uma das etapas do procedimento de obtenção da resistividade do solo.
