Random assignment increases the chance that characteristics other than the independent variable will be equally distributed across treatment groups, as it involves assigning participants to groups randomly, which helps to reduce any bias or confounding factors. Manual or predetermined distribution may result in non-random assignment and may potentially introduce bias into the study. Natural assignment also does not involve randomization and may result in non-equivalent treatment groups. Therefore, random assignment is the best choice for ensuring equal distribution of characteristics across groups.
