    • Reliability
    • Replication
    • Validity
    Judging research Part I: The Quantitative Edition
  • 6.
    • Dependability
    • Confirmability

    • Experimental design
    • Cross sectional
    • Longitudinal
    • Case study
  • 8. A “variable” varies…
  • 9. What is varying?
  • 10. Independent vs Dependent Variables Age Height ?

  • 13. Cross-sectional Design All exam grades Studying “goes with” higher grades “ A” grades Studied for hours or more “ B” and below Studied for less than 2 hours
  • 14. Longitudinal Design Random group of people Surveyed about drug use All people born in 1960 Surveyed about drug use 1960 1980 Surveyed again about drug use Surveyed again about drug use 1970 Cohort study Panel study
  • 15. The Case Study Unique! Revelatory! Critical! Interesting and available
  • 16. Research Designs and Validity Weak Potentially weak Case study Potentially weak Potentially weak Strong Internal validity Strong (if done right) Longitudinal Strong (if done right) Cross-sectional Potentially weak Experiment External validity
