I am interested in whether different types of therapy result in faster recover. I follow 7 different therapists using a different type of therapy and 20 patients in each condition and I record how long it takes for them to be cured. As you can imagine, I cannot determine who goes to which therapist and thus there is no random assignment of patients. What kind of research method am I using?
