The t-test procedure performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given number (which you supply). The independent samples t-test compares the difference in the means from the two groups to a given value (usually 0). In other words, it tests whether the difference in the means is 0. The dependent-sample or... To examine the research question, an independent sample t-test will be conducted to assess if differences exist on a dependent variable by an independent variable. An independent samples t -test is the appropriate statistical test when the purpose of research is to assess if differences exist on a continuous (interval/ratio) dependent variable by a dichotomous (2 groups) independent variable.

## How To Write Independent Samples T-test Results

### Independent Samples t-test Results • In order to test the efficacy of the new psychotherapy intervention for self-injury, an independent samples t-test was conducted. This test was found to be statistically significant, t(15) = -3.07, p < .05; d = 1.56. The effect size for this analysis (d = 1.56) was found to exceed Cohen’s (1988) convention for a large effect (d = .80). These results

- The two sample t test yields a statistic t, in which X-bar, of course, is the sample mean, and s is the sample standard deviation. Note that the numerator of the formula is the difference between means.
- There is a t-test for dissertations involving experimental designs with randomized groups (independent samples), and another t-test for dissertations with experimental designs involving correlated groups (matched pairs or within-subjects designs). Knowing what kind of sample you have is key to selecting the appropriate t-test for your analyses.
- Part III deal s with interpreting t-test results. Part II: Conducting a t-test (for Independent Means) So how do we test a null hypothesis? One way is with a t-test. A t-test asks the question, “Is the difference between the means of two samples different (significant) enough to say that some other characteristic (teaching method, teacher, gender, etc.) could have caused it?” To
- Since the two-sample t-test presupposes equality of variances, often a preliminary F-test is advised to check this assumption. However, very large sample sizes are necessary before this procedure
