Question

Quizplus · Accepted Answer

The information provided does not specify whether the samples are dependent (paired) or independent. The degrees of freedom (df) and t value alone cannot determine the design type without additional context, such as whether the same subjects were measured under different conditions (paired) or if two separate groups were compared (independent).
