The 5 research methods done by sara amin and julia khlaifat
Sara Amin and Julia Khlaifat's work delves into five distinct research methods, focusing on naturalistic observation, correlation studies, and case studies, among others. Naturalistic observation involves studying behaviors in their real-life settings without direct interference, offering an unobstructed view of natural behavior, though it faces challenges like difficulty in replication and lack of control.
