Which statement describes a well-designed experiment?

• A. It relies on untested ideas.
• B. It uses only one data point.
• C. It identifies a question, forms a hypothesis, designs the experiment, collects data, and analyzes results.
• D. It avoids data collection.

Answer: (C)

The main concept being tested is applying the scientific method in a structured, testable way. A well-designed experiment follows a clear sequence: identify a specific question, form a testable hypothesis, plan and conduct an experiment with careful controls, collect data, and analyze the results to reach a conclusion. This sequence ensures that ideas can be tested, measurements are evidence-based, and findings can be reproduced. This option reflects that whole process, showing how a question leads to a hypothesis, a concrete experimental plan, data collection, and data analysis. In contrast, relying on untested ideas offers no way to verify them; using only one data point provides insufficient evidence for conclusions; and avoiding data collection eliminates the evidence needed to determine whether the hypothesis is supported. A well-designed experiment hinges on that structured flow from question to data-driven analysis.
