Final answer:
Deviation from social norms provides a clear and objective way to define abnormality, allowing behaviors that deviate from societal expectations to be identified while considering the cultural context.
Step-by-step explanation:
One strength of deviation from social norms as a definition of abnormality is that it provides clear and objective criteria. When measuring abnormality based on social norms, behaviors that are considered to deviate from what is expected or typical within a given society can be identified. This approach does consider the context and cultural factors affecting what is deemed as normal or deviant. As behaviors vary significantly between cultures, what is considered normal in one society might be seen as abnormal in another, thus emphasizing cultural relativity. An example of this could be the difference in behaviors deemed appropriate at funerals across various cultures.
