What is the purpuse of hyphotesis?

The purpose of a hypothesis is to provide a testable prediction or explanation for a phenomenon, serving as a foundational element in scientific research. It guides the direction of an investigation by outlining what the researcher expects to find based on existing knowledge. By formulating a hypothesis, researchers can design experiments or studies to gather data, ultimately supporting or refuting the proposed idea. This process helps advance understanding in a particular field and contributes to the broader body of scientific knowledge.
