What is a hypothesis typically formulated from?

A hypothesis is typically formulated from observations and prior knowledge because it is essentially an educated guess or a proposed explanation for a phenomenon based on what one already knows and has observed. This process draws on existing information, insights, and data to establish a basis for further investigation. By using observations, scientists can identify patterns, relationships, or anomalies in nature, which prompts them to formulate a hypothesis that can then be tested through experimentation.

Observations allow researchers to notice specific phenomena and generate questions, while prior knowledge provides the necessary context and understanding to create a plausible and testable hypothesis. This is a fundamental aspect of the scientific method, as it encourages a systematic and logical approach to inquiry, rather than relying on random guesses, which lack a foundational basis. In contrast, experiments and scientific theories come into play at later stages of the scientific process, where hypotheses are tested and refined or supported by broader theories.
