How is a hypothesis different from a theory?

• A. A hypothesis is a testable prediction, while a theory is a well-substantiated explanation
• B. A hypothesis is a proven conclusion, while a theory is a supposition
• C. A hypothesis is a longer term belief, while a theory is short-term
• D. A hypothesis is derived from theories that lack evidence

Answer: (A)

A hypothesis is fundamentally a testable prediction that serves as a starting point for scientific investigation. It proposes a specific relationship or outcome based on existing knowledge and observations and can be verified or disproved through experimentation. In this sense, the hypothesis plays a critical role in the scientific method, guiding researchers in their inquiries and experiments.

On the other hand, a theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and extensive testing over time. Theories are broader in scope than hypotheses and can encompass multiple hypotheses that have been supported by extensive research. They explain why and how certain phenomena occur, offering a comprehensive framework that is consistent with the data collected through scientific research.

Thus, the distinction between a hypothesis and a theory is clear: a hypothesis is an initial, testable statement predicting an outcome, while a theory represents a comprehensive understanding supported by substantial evidence.
