What systematic approach is used to test ideas in science?

• A. The scientific method
• B. Experimental design
• C. Hypothesis testing
• D. Observational method

Answer: (A)

The systematic way to test ideas in science is the scientific method. This structured approach guides scientists from asking a question to making a testable prediction, planning and conducting experiments or observations, collecting and analyzing data, and drawing conclusions that are shared with others. It emphasizes repeatable procedures and evidence-based reasoning, so ideas are tested fairly and conclusions reflect what the data show. Experimental design is about planning how to run experiments to get reliable results, but it’s just part of the process. Hypothesis testing focuses on evaluating a specific prediction, which is a step within the broader method. Observational methods involve gathering data without manipulating conditions, which can be part of science but does not by itself constitute the full, systematic testing framework.
