This p-value calculator helps you to quickly and easily calculate the right-tailed, left-tailed, or two-tailed p-values for a given z-score. It also generates a normal curve and shades in the area that represents the p-value.
Powerful p-value calculator online: calculate statistical significance using a Z-test or T-test statistic (z test calculator / t-test calculator). P-value formula, Z-score formula, T-statistic formula and explanation of the inference procedure.
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.
Here’s how the z-score and p-value help in decision-making: Calculate the z-score: The z-score for the 5.2 cm screw is calculated as (5.2 - 5) / 0.1 = 2.0. Determine the p-value: Using the z-score, the factory calculates the p-value. A low p-value (e.g., less than 0.05) indicates that the screw’s length is statistically different from the ...
