In an independent-samples design, the participants in the two groups are different individuals with no logical pairing between them. This contrasts with a paired-samples design, where each participant in one group is matched or paired with a participant in the other group based on certain criteria, making D the correct choice. Type I and Type II errors are statistical concepts that can occur in any experimental design, and confidence intervals can be calculated for independent samples to estimate the difference between group means.
