A cognitive retraining clinic assists outpatient victims of head injury
A cognitive retraining clinic assists outpatient victims of head injury, anoxia, or other conditions that result in cognitive impairment. Each incoming patient is evaluated to establish an appropriate treatment program and estimated length of stay (ELOS is always a multiple of 4 weeks because treatment sessions are scheduled on a monthly basis). To see if there is any difference in ELOS between the two clinics, a sample is taken, consisting of all patients evaluated at each clinic during October, with the results shown. Research question: At α = .10, do the medians differ?
