Question

The decision is to reject the null hypothesis for the following related-samples t test: t(23)= 2.25,p < .05 (d = 0.18).

Quizplus · Accepted Answer

The decision to reject the null hypothesis (assuming it was a two-tailed test) is based on the calculated t-value being greater than the critical t-value at an alpha level of .05 (which is 2.07 for 23 degrees of freedom). Additionally, the effect size (d = 0.18) indicates a small but statistically significant difference between the related samples being compared.
