Document Summary
Review of the scientific method: generate a question of interest, formulate a (justified) hypothesis, develop/select a method, draw a conclusion based on the data. Select a method means coming up with your plan with how you will test your hypothesis. Finish with a posttest measure to assess effect of treatment intervention. The value of a given study is limited by the quality of the measurement tools . Reliability: the extent to which there is consistency in the measurement of some behaviour (independent measurements, multiple independent tasks). A tool that is reliable is one that is consistent. Inter-rater reliability: the degree to which multiple raters provide consistent ratings of the same behavior. You want to have confidence that the assessments provided by individuals doing the ratings are reliable. Contrast qualitative (the friendly or hostile behaviours) vs. quantitative (we want to measure/count how frequent an action is) ratings.
