**T-Test:** This test is most commonly applied when the test statistic would follow a normal distribution if the value of a scaling term in the test statistic were known. When the scaling term is unknown and is replaced by an estimate based on the data, the test statistic (under certain conditions) follows a Students t distribution.

Make use of this **online T test calculator** to calculate the T-value, mean and variance based on the entered values of the first set of values and the second set of values with ease. This t-test calculator can process any range of inputs in uniformly same time.
