T Statistic Calculator (T-Value) Enter the sample mean, population mean, standard deviation, and sample size into the t statistic calculator to determine the t-value of that set of data. Welcome to the critical value calculator! 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. Our calculator determines the p-value from test statistic, and provides the decision to be made about the null hypothesis. The standard significance level is 0.05 by default.
