WebbEsta función produce un estadístico de prueba W junto con un valor p correspondiente. Si el valor p es menor que α = .05, hay evidencia suficiente para decir que la muestra no proviene de una población con distribución normal. Nota: El tamaño de la muestra debe estar entre 3 y 5,000 para poder usar la función shapiro.test (). WebbO Shapiro Wilk é um teste para aferir a normalidade dos dados (se a variável segue uma distribuição normal). A avaliação do pressuposto de normalidade é exigida pela maioria dos procedimentos estatísticos. A análise estatística paramétrica é um dos melhores exemplos para mostrar a importância de avaliar a suposição de normalidade. orange clove halal buffet https://2brothers2chefs.com
