Random Assignment

Random assignment is a method used in research to ensure that participants are placed into different groups in a way that is completely by chance. This process helps ensure that each group is similar at the start of the study, allowing researchers to make fair comparisons between them. By randomly assigning participants, differences in outcomes can be attributed to the treatments or conditions being tested, rather than any pre-existing differences among the participants. This technique enhances the validity of the study's findings, making it easier to draw reliable conclusions about the effects being studied.
