Document Summary
Approaches: want to avoid misconceptions & error, adapt scientific attitude. Sampling & generalization: who should be included in a study, individuals with similar behavioral abnormalities, mirrors the underlying population, large/randomly selected gives a good general representation. Basic components: hypothesis (based on past research, you cannot prove a hypothesis right, but it can be supported, you can prove a hypothesis wrong research design independent variable (manipulated, dependent variable (measured interest of study) Scientific method: question must be new (most difficult part) 2. theory relationship between behavior & mental processes (take in past research: hypothesis must be testable, collect data iv & dv. 5. theory/draw conclusions based on observations, support or proved wrong: share/report works on the honor system. Statistical significance: used in research to determine if numbers are really different & if change has really taken place, if p< . 5 , then there is a difference.
