t-test for independent samples A two tailed t-test for independent samples (equal variances assumed) showed that the difference between yes and no with respect to the dependent variable ABUSE was not statistically significant, t(5622) = 0.51, p = .613, 95% confidence interval [-0.46, 0.78]. Thus, the null hypothesis was not rejected.Report the relevant statistics based on the SPSS output, indicating t, p, and df using the correct notation (see page 206). Indicate if t is statistically significant. Also, compute the effect size (ES), and indicate if it is small, medium, or large (see page 196)
