WebbSimilarly, Shapiro–Wilk test (P = 0.454) and Kolmogorov–Smirnov test (P = 0.200) were statistically insignificant, that is, data were considered normally distributed. As sample size is <50, we have to take Shapiro–Wilk test result and Kolmogorov–Smirnov test result must be avoided, although both methods indicated that data were normally distributed. WebbEn estadística, la prueba de Shapiro–Wilk se usa para contrastar la normalidad de un conjunto de datos. Se plantea como hipótesis nula que una muestra proviene de una población normalmente distribuida. Fue publicado en 1965 por Samuel Shapiro y Martin Wilk. 1 Se considera uno de las pruebas más potentes para el contraste de normalidad.
