Document Summary
A scientific hypothesis must be testable (not all hypothesis are). Research design is a method to test a hypothesis. It has an independent variable and a dependent variable. Striking a balance in the relationship between internal validity and external validity. Minimizing cofounds in the control groups, randomization, and statistical versus clinical significance. Statistical methods: branch of mathematics and reduces biases. Etiology- the study of why a disorder begins. Multiple causation- biology, psychology, learning history, culture, and social factors. Extensive observation, detailed description, foundation for early developments (freud), unique problems, contributions/challenges to theories, limitations (reactivity), research by correlation. Statistical relationship, no manipulated independent variables, may involve continuous (dimensional) or non-continuous (categorical) variables. Directionality (not sure which variable affects which) and third variables. Matched control groups: controls the impact of confounds such as age, Placebo control group: controls the impact of expectancy effects. Single-blind (patients do not know what group they are in) group the individuals are in)
