USE IN A SENTENCE
Researchers use randomization to make sure that study groups are similar and chosen fairly.
Every participant has a chance to be put into one of the study groups. No one can choose which group a participant is placed in, because it is done by a computer program.
Randomization helps make sure the study groups can be compared against each other at the end of the study. This is a way to avoid bias.
