PSYB01H3 Lecture 3: PSYB01 - Lecture 3 Notes
Document Summary
Describe the different steps involved in the research process. Define variable and describe the four categories of variables: situational, response, participant, and mediating variables. Describe the different relationships between variables: positive, negative, curvilinear, and no relationship. Compare and contrast non-experimental and experimental research methods. Distinguish between an independent variable and a dependent variable. Discuss the three elements for inferring causation: temporal order, covariation of cause and effect, and elimination of alternative explanations. Discuss the limitations of laboratory experiments and the advantage of using multiple methods of research. Distinguish between construct validity, internal validity, and external validity. The research process: research idea: topic library research hypothesis, define and measure variables: must be reliable and valid. Factorial design: do the study (collect your data, analyze your data (descriptive and inferential statistics, write paper (apa ; remember ethical considerations, assess original idea: alter, refine, expand (gravetter & forzano, 2009, p. 26) Should be able to observe and measure all important variables.
