An effect size measure is the best choice to assess the practical importance of the obtained results in a paired-samples t test. This measure expresses the magnitude of the difference between the means of the two paired samples, independent of sample size. It can be used to determine whether the effect size is significant and meaningful in practical terms. The options of hypothesis test, post-hoc tests, and confidence interval are all statistical procedures that are used to interpret the significance of the obtained results, but they do not directly assess the practical importance of the results.
