Truth being in accordance with fact or reality. Scientific approach---evidence approach based, systematic, logical, reliable, and valid conclusions. Typical error in non-scientific approach : measurement may not actually measure what we want to measure. Self- reported health vs. physical exam: conclusions may not generalize to the population. How researchers examine the question: different types of methods of data. Procedures verify, refute, or validate the hypothesis o: rigorous or the golden standard to establish the cause effect interference.

Observational study: most common in social sciences research treatment is not manipulable, gender, ethnicity, socio-economic status, height.
