Which statement best describes a hypothesis?

• A. A testable explanation or interpretation that can be verified or falsified
• B. A casual belief without evidence
• C. A data analysis method
• D. A final proven fact

Answer: (A)

In science, a hypothesis is a proposed explanation that can be tested through observations or experiments. It is a testable explanation or interpretation that can be verified or falsified by data, which is what allows us to evaluate it objectively rather than rely on guesswork. This is why it stands apart from casual beliefs without evidence. It’s also different from a data analysis method, which is a tool for examining data but does not itself make a claim about how the world works. And it isn’t a final proven fact; a hypothesis can be supported by evidence but remains open to revision or rejection as new data come in. A good hypothesis makes a specific, testable prediction so you know exactly what to look for when testing it. For example, if a mineral dissolves faster in acidic water, you should observe a higher dissolution rate in acidic conditions than in neutral conditions.
