This test is known as an a two sample (or unpaired) t-test. It produces a “p-value”, which can be used to decide whether there is evidence of a difference between the two population means. The p-value is the probability that the difference between the sample means is at least as large as what has been observed, Instructions: This calculator conducts a t-test for two paired samples. This test applies when you have two samples that are dependent (paired or matched). Please select the null and alternative hypotheses, type the sample data and the significance level, and the results of the t-test for two dependent samples will be displayed for you: Ho: 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. The mean in statistics refers to the average that is used to derive the central tendency Two samples t-Test.
