In research, empirical evidence is primarily derived from

• A. theory and deduction
• B. personal beliefs
• C. observation or experiment
• D. peer opinion

Answer: (C)

Empirical evidence comes from what we can observe, measure, and test in the real world. In research this means collecting data through observation or through experiments where variables are controlled and outcomes are recorded. These approaches yield concrete, checkable results that others can replicate, which is why they form the bedrock of empirical evidence. Theory and deduction are crucial for forming hypotheses and interpreting results, but they rely on data gathered from observation or experimentation to be validated. Personal beliefs or peer opinions are subjective and cannot be verified through independent observation or controlled testing, so they don’t count as empirical evidence.
