Calcula a estatística Qui-Quadrado e o valor p para a adequação do ajuste ou teste de independência. Requer frequências ou valores observados e esperados.

Calculadora Qui-Quadrado gives you a faster way to work through practical calculation scenarios without rebuilding the same calculation from scratch every time. Start with Valores Observados (separados por vírgula) and Valores Esperados (separados por vírgula) and use the live outputs to estimate Estatística Qui-Quadrado, Graus de Liberdade, and Valor P (Aproximação) in one pass. This page is built to help you compare scenarios quickly, validate rough assumptions, and move into a related calculator when you need a second angle on the same problem.
