Sources must be peer reviewed articles. I am attaching the assignment details. The assignment is to fill out a concept chart with at least 25 peer reviewed articles that I will be using for my single study research paper for my doctoral program. Another writer helped me to write the literature review and methods for the study. I can email an excel file of what I have finished already, but for some reason, I can’t attach it on this screen. I also have all the sources and I can email them, but I don’t think it will allow me to attach them on this screen.
