Same as Student's t-test.

An hypothesis test based on approximating the probability histogram of the test statistic by Student's t curve. t tests usually are used to test hypotheses about the mean of a population when the [..]

This test is applied to prove that the null hypothesis is true. T test is important when we have start doing a research in any area or subject. We are able to know that the null hypothesis is justifie [..]

The t test is a statistical test which computes the probability (p) that two groups of a single parameter are members of the same population. The population must follow a t distribution. However, a t test is robust enough to allow considerable deviation from normality.

A test of variable significance in least squares and other estimation methods, a t statistic is computed as the ratio of a variable's estimated coefficient to the standard error of that coefficie [..]

A statistical test that is used to find out if there is a real difference between the means (averages) of two different groups. It is sometimes used to see if there is a significant difference in response to treatment between groups in a clinical trial.

Statistical test that helps to show if there is a real difference between different treatments being tested in a controlled clinical trial.
