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.
30 paź 2024 · Jeśli rozkład statystyki testowej (pod warunkiem prawdziwości H 0) jest symetryczny względem 0, to wzór na dwustronną wartość p można uprościć do postaci p-wartość = 2 · cdf (-|x|), lub, równoważnie, p-wartość = 2 - 2 · cdf (|x|).
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).
Calculator to compute p-value from Z-score or Z-score from p-value for a normal distribution. It also provides a diagram illustrating the area of the p-values.
P-value Calculator. Statistical significance calculator to easily calculate the p-value and determine whether the difference between two proportions or means (independent groups) is statistically significant.
27 cze 2024 · You can use this our calculator to calculate the P value from T score statistics (and the correct degrees of freedom). Both positive and negative values of T will give the same result, and P values are interpreted similarly for all T tests.
