A P-value calculator is used to determine the statistical significance of an observed result in hypothesis testing. It takes as input the observed test statistic, the null hypothesis, and the relevant parameters of the statistical test (such as degrees of freedom), and computes the p-value.
Calculadora de valor P. Encuentre el valor p para diferentes distribuciones. La calculadora encontrará el valor p para las pruebas de dos colas, cola derecha y cola izquierda de las distribuciones normal, Student (distribución T), chi-cuadrado y Fisher (distribución F). Choose a distribution: Enter a statistics: Choose type:
The p-value calculator will output: p-value, significance level, T-score or Z-score (depending on the choice of statistical hypothesis test), degrees of freedom, and the observed difference. For means data it will also output the sample sizes, means, and pooled standard error of the mean.
A calculadora encontrará o valor-p para testes bicaudais, à direita e à esquerda das distribuições normal, de Student (distribuição T), qui-quadrado e Fisher (distribuição F). Choose a distribution: Normal (z-value) Student's (t-value) Chi-squared F (Fisher–Snedecor)
23 lut 2015 · The e is standard scientific notation for powers of $10$: 8.6e-28 means $8.6 \cdot 10^{-28}$. The White test tests for heteroscedasticity of a variable's distribution, most commonly in the residuals of your regression.
Introduce el valor del estadístico de prueba para tu muestra de datos. Nuestra calculadora determina el valor p del estadístico de prueba y proporciona la decisión a tomar sobre la hipótesis nula. El nivel de significación estándar es 0.05 por defecto.
