A clinical psychologist wants to test the effectiveness of three new therapies that have been developed for reducing anxiety symptoms. The researcher recruits 15 participants and randomly assigns them to take part in Therapy A, Therapy B, or Therapy C for a month. At the end of the month, the researcher measures the participants' anxiety symptoms on a scale from 1 to 10 (where a higher score means more anxiety symptoms). The participants' scores are shown below: Therapy A 2 4 3 3 3 Therapy B 6 5 5 7 2 MTherapyA= 3.00 MTherapyB = 5.00 MGrand= 5.00 Therapy C 9 7 6 6 7 MTherapyc = 7.00 Using the appropriate hypothesis test and the six steps of hypothesis testing, see what the researcher should conclude about how the therapies compare in their ability to reduce anxiety symptoms.
