an experiment arranged to produce a chance distribution of subjects into different treatment or control arms. Randomization is done to cancel out the influence of factors that are not under study. With successful randomization, the chance of one individual being placed in a given study arm is independent of the placement of others, and the only differences between the groups are those intended by the experimenter (e.g., different drugs taken).
