The degrees of freedom (df) for an independent-measures t-test is calculated by adding the degrees of freedom from each sample and then combining them. For each sample, df = n - 1. So, for the first sample, df = 10 - 1 = 9, and for the second sample, df = 15 - 1 = 14. Adding these together gives 9 + 14 = 23.
