Sampel Independen T Test. The independent samples t test is the between subjects analog to the dependent samples t test which is used when the study involves a repeated measurement e g pretest vs. If the population means are really equal then the sample means will probably differ a little bit but not too much.
The independent samples t test is a parametric test. Examples of typical questions that the independent samples t test answers are as follows. A t test is used when you re looking at a numerical variable for example height and then comparing the averages of two separate populations or groups e g males and females.
If the population means are really equal then the sample means will probably differ a little bit but not too much.
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 two samples should have the same variance. The independent samples t test is a parametric test. The independent samples t test is the between subjects analog to the dependent samples t test which is used when the study involves a repeated measurement e g pretest vs.
