  The Independent Samples t Test compares the means of two independent groups in order to determine whether there is statistical evidence that the associated population means are significantly different. The Independent Samples t Test is a parametric test. This test is also known as: Independent t Test Independent Measures t Test Independent Two-sample t Test Student t Test Two-Sample t Test Uncorrelated Scores t Test Unpaired t Test Unrelated t Test The variables used in the test are known as: Dependent variable, or test variable Independent variable, or grouping variable The Independent Samples t Test is commonly used to test the following: Statistical differences between the means of two groups Statistical differences between the means of two interventions Statistical differences between the means of two change scor...
