## Cálculos Estatísticos em PHP

Esta é uma classe em PHP que contém funções que implementam alguns cálculos estatísticos. Os algoritmos que representam as fórmulas estatísticas estão escritos em uma estrutura simples e semelhante a aplicação pura das respectivas fórmulas, para deixar o código o mais limpo possível, e assim, didático.

Até o momento, estas são algumas das fórmulas estatísticas que estão implementadas:

![Media1](img/media1.png?raw=true)

![Media2](img/media2.png?raw=true)

![Media3](img/media3.png?raw=true)

![Dispersao1](img/dispersao1.png?raw=true)

![Dispersao2](img/dispersao2.png?raw=true)

![Dispersao3](img/dispersao3.png?raw=true)

![Dispersao4](img/dispersao4.png?raw=true)

![Dispersao5](img/dispersao5.png?raw=true)

Obs.: As funções possuem versões para dados agrupados ou não agrupados e para dados amostrais ou populacionais. Esta classe não utiliza a extensão PECL "stats" pois a ideia é demonstrar os algoritmos.
