Independent Samples t Test. 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.he calculated t value is then compared to the critical t value from the t distribution table with degrees of freedom df = n 1 + n 2 - 2 and chosen confidence level. If the calculated t t value, then we reject the null hypothesis. Note that this form of the independent samples T test statistic assumes equal variances.
The Independent t Test procedure compares means for two groups of subjects. If the significance value for the Levene test is high (greater that 0.05), use the. results that assume equal variances for both groups. Otherwise, Use the results. that do not assume equal variances for both groups. In our case, the equal.
