A completely randomized design is the most appropriate experimental design when there is no particular reason to group or block the experimental units. Random assignment of units to treatments helps to ensure that any observed differences between the treatment groups are due to the treatments themselves rather than any systematic differences between the groups at the outset of the experiment. In other words, it helps to control for confounding variables that might otherwise influence the outcome of the study.
