Random assignment is the process of assigning participants to different groups in an experiment randomly. This helps to eliminate any potential bias and ensures that any differences observed between groups are due to the independent variable being manipulated, rather than individual differences between participants. Therefore, random assignment is the most important component of an experiment for giving us confidence that our results are meaningful.
