T Statistic Calculator for Two Samples

The mean in statistics refers to the average that is used to derive the central tendency of the data. It is calculated by adding all the data in a population and then dividing the total by the number of points. The resulting number is called as the mean or the average. Two means can be compared to find the t-statistic. Here is the online T statistic calculator for two samples which provides you the standard error, pooled standard deviation, and t-statistic for the 2 samples.

Formula:

Pooled Standard Deviation (r) = √( (n1 - 1) σ12 + (n2 - 1)σ22 / (n1 + n2 - 2) ) Standard Error (S) = R x √(1 / n1) + (1 / n2) T - Statistic = μ1 - μ2 / S Where, μ1 = Mean1 σ1 = Standard Deviation1 n1 = Sample Size1 μ2 = Mean2 σ2 = Standard deviation2 n2 = Sample size2

Just enter the inputs of two samples in the above T statistic calculator for two Samples and click calculate to get the result. The above method calculates the difference between the observed means in two independent samples.
