Summary A control‐versus‐treatment multiple comparison test procedure is developed based on ranked set samples. The test, constructed based on K ‐independent exact median confidence intervals corresponding to the K populations, rejects the null hypothesis of equal medians if the median confidence intervals of the control group and any one of the other K − 1 treatment groups are disjoint. The use of the proposed test is illustrated with data from an agricultural experiment.
