Two different medications are to be compared in the treatment of depression among elderly patients in an assisted living facility. Each patient has his or her own room, but for safety concerns some are restricted to a phone only for in-house calls and some are allowed a phone that can call outside the facility. Which of the following would result in a randomized block design with blocks based on type of phone? (A) Within patients that have the same type of phone, randomly assign half to each medication. (B) Within patients taking the same type of medication, randomly assign half to each type of phone. (C) Randomly assign all patients with phones that can call outside the facility to take one medication and have all patients with phones only for in-house calls take the other medication. (D) Randomly assign all patients on one medication to phones that can call outside the facility and all patients on the other medication to phones only for in-house calls. (E) Allow patients to choose which medication they prefer, and then compare the two medications within patients that have the same type of phone.
