A repeated-measures design would produce 20 scores in each treatment because in this design, each participant is measured under both treatment conditions, resulting in a set of scores for each participant in each treatment. Therefore, with 20 participants, there would be 20 scores in each treatment condition. The other options (independent-measures and matched-subjects designs) would not necessarily result in 20 scores in each treatment condition, as both of these designs involve comparing two separate groups of participants rather than having each participant provide scores in both treatment conditions.
