In a within-subjects design, each participant experiences all conditions, and researchers test the same participants repeatedly for differences between conditions. In a between-subjects design, every participant experiences only one condition, and researchers assess group differences between participants in various conditions. Counterbalancing (randomising or reversing the order of treatments among subjects) is often used in within-subjects designs to ensure that the order of treatment application doesn’t influence the results of the experiment. Randomly allocating participants to independent va
