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.
For a hypothesis test with an independent-measures t, the larger the difference between the two sample means, the greater the likelihood that you will reject the null hypothesis. 2. One sample with n = 8 and a second sample with n = 10 will produce an independent-measures t statistic with df = 9. 3. For a two-tailed hypothesis with an independent-measures t statistic using two samples, each with n = 10 scores, the boundaries for the critical region using a = .05 are t = Â±2.101. 4.
