This calculator will conduct a complete one-sample t-test, given the sample mean, the sample size, the hypothesized mean, and the sample standard deviation. The results generated by the calculator include the t-statistic, the degrees of freedom, the critical t-values for both one-tailed (directional) and two-tailed (non-directional) hypotheses, and the one-tailed and two-tailed probability In statistics, a test used to compare the two means and find if they differ from each other, for a large sample size with known variance value is called as z test. This is an online calculator to find the z-score for a set of data with the standardized random variable, population mean and standard deviation.
