Compute your T-score value: Formulas for the test statistic in t-tests include the sample size, as well as its mean and standard deviation. The exact formula depends on the t-test type — check the sections dedicated to each particular test for more details. Determine the degrees of freedom for the t-test:
- P-value
Formally, the p-value is the probability that the test...

The critical value calculator is an easy-to-use tool for determining critical value whether it is a one-tailed test or two-tailed test. Test type : in this fields enter the type of test from z-score, t-score, chi-square \( \chi^2 \), F-score or correlation coefficient r.
16 wrz 2024 · Here you can quickly determine the critical value (s) for two-tailed tests, as well as for one-tailed tests. It works for most common distributions in statistical testing: the standard normal distribution N (0,1) (that is when you have a Z-score), t-Student, chi-square, and F-distribution.
To calculate the Z test statistic: Compute the arithmetic mean of your sample. From this mean subtract the mean postulated in null hypothesis. Multiply by the square root of size sample. Divide by the population standard deviation. That's it, you've just computed the Z test statistic!
Use this calculator for critical values to easily convert a significance level to its corresponding Z value, T score, F-score, or Chi-square value. Outputs the critical region as well. The tool supports one-tailed and two-tailed significance tests / probability values.
By supplying corresponding input values to this critical value for t-test calculator, users can estimate t e) for single independent sample mean (x̄), difference between two sample means (x̄ 1 - x̄ 2) & paired or related sample means (x̄) in statistical surveys or experiments.
The easy-to-use hypothesis testing calculator gives you step-by-step solutions to the test statistic, p-value, critical value and more.
