In a between-subjects experimental design, eachparticipantis assigned to one condition of theexperiment.A between-subjects experimental design involvesassigningparticipants to different conditions of the experiment, with each participantexperiencingonly one condition. Therefore, option b, "Each participant is assigned to one condition of the experiment," bestcharacterizesa between-subjects design.The purpose of a between-subjects design is to compare the effects of different conditions or treatments by having separate groups of participants experience each condition. This allowsresearchersto assess the differences in outcomes between the groups and attribute those differences to thespecificcondition being tested.Assigning participants to only one condition helps control for confounding variables and reduces thepotentialinfluence of individual differences. Each participant serves as an independent data point, contributing to the overall analysis of the experimental design. This design allows forstraightforwardcomparisons between conditions and facilitates the identification of the specific effects of each condition on the dependent variable.In contrast, options a, c, and d do notaccuratelycharacterize a between-subjects design. Option A refers to a random selection from different populations, which is not a characteristic of this design. Option c suggests that each participant experiences every condition, which is characteristic of a within-subjects design. Option d implies that participants with the same characteristics are assigned to different conditions, which is not a defining feature of between-subjects designs.Learn more aboutexperimenthere :brainly.com/question/15088897#SPJ11...
