  2. Research Methods • When studying social science, we look at two kinds of evidence • Quantitative: gives us #’s, uses statistics • Qualitative: understands through direct observation

  3. Research Methods • When looking at quantitative research: • Is it possible to poll the entire population? • In social science, we use the idea of samples • Sample: Use a subset of the population to draw inferences from • Example of qualitative research: Surveys

  4. Research Methods • When looking a qualitative research • Offers detailed evidence, but typically cannot be generalized • Examples: Case studies and participant observation

  5. Research Methods: Bias • Common mistakes made in social science: • i) Selection Bias • sample does not represent population • ii) Measurement Bias: • errors in collecting data; expectation bias, attention bias, • iii) Intervention Bias • Typically occurs when comparing groups

  6. Research Methods • Validity: extent to which a test measures what it says it’s going to measure • Reliability: consistency of a measure.

  7. Ethics • A note on ethics . . . • informed consent: subjects must be informed of risks and procedures • risk of harm: both psychological and physical • confidentiality: identifying information not released to anyone outside study
