"Normal" or "Standard" refers to a baseline or typical condition that is widely accepted or expected in a given context. It serves as a reference point for comparison, helping to identify variations or deviations. In various fields, such as science, psychology, and sociology, "normal" can describe behaviors, measurements, or phenomena that fall within a common range. In everyday life, "normal" often relates to social norms, which are the unwritten rules that govern behavior in a society. These norms can vary significantly across cultures and communities, influencing what is considered acceptable or typical. Understanding "normal" helps individuals navigate social interactions and expectations.
