t is test statistics in hypothesis testing. Calculator - Standardized Test Statistic 2020-06-15 · 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. 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.
