Calculate The T Statistic. Then we enter the t statistic -04276 and the degrees of freedom 13 into the calculator and hit the Calculate button. After entering these values the T score calculator will generate the T value right-tailed and the T value two-tailed. T-statistic calculator uses t_score Sample mean-Population meanStandard Deviation sqrt Sample Size 1 to calculate the t_score The t-statistic formula is defined by the formula t x- μ s sqrt n where x is the mean of sample μ is the mean of population s is the standard deviation and n is the sample size. Calculate the T-statistic Divide s by the square root of n the number of units in the sample.
The t is pretty similar to the z in fact its almost identical. Here are the steps to use this calculator. T x μ s sqrt n Where X is the sample mean μ is the population mean. The t-value measures the size of the difference relative to the variation in your sample data. T 0 is an important part of t-test to test the significance of small samples. The formula to calculate the test statistic comparing two population means is Z x -.
