Chapter 1Intro to Scientific Research
• What is a theory?• Methods of conducting science– Induction/Deduction– Hypothesis Testing– Naturalism
• Assumptions Underlying Research– Determinism– Reality in Nature– Discoverability
Chapter 2Research Approaches and Data Collection Methods
• Non-experimental quantitative research• Claiming cause and effect• Psychological experiment• Quantitative vs. Qualitative Research• Mediator/Moderator• Experimental research settings
Chapter 3Problem Identification and Hypothesis Formation
• Parts of a research paper• Sources of research ideas
– Literature review• Research idea, research problem/question, hypothesis• Order of operations
– get research idea– review the literature– determine feasibility of study– formulate the research problem– formulate the hypothesis– collect the data
Chapter 5Measuring Variables & Sampling
• Scales of Measurement• Reliability• Validity • Relationship between reliability & validity• Sampling– Benefits of random sampling
Chapter 6Research Validity
• Types of validity• Threats to validity
* Internal/External validity– relationship between
Chapter 4Ethics
• Areas of ethical concern• Informed Consent• Assent• Debriefing• Role of IRB
Chapter 8Experimental Research Design
• Weak experimental designs– What’s missing?
• Strong experimental designs– What makes them strong designs?
• Between-participant designs• Within-participant designs• Factorial designs
Chapter 7Control Techniques in Experimental Research
• Random assignment vs. random selection• Control by matching– For what kind of design?
• Counterbalancing– For what kind of design and what kind of effects?
• Control for Participant Effects• Control for Experimenter Effects
Chapters 14 & 15Statistics Review
• Inferential Statistics• Graphical representation of data• Measures of Central Tendency• Nature of hypothesis testing– Type I / Type II error
• What’s the appropriate statistical test?– Correlation -- one-way ANOVA– Ind. Samples t test -- factorial ANOVA– Paired samples t test
Chapter 10Quasi-Experimental Designs
• Where do quasi-experimental designs fit in the continuum of weak to strong designs?
• What is the primary difference between quasi- and strong experimental designs?
• What conditions are required to infer causation from quasi-experimental designs?
Chapter 11Single-Case Research Designs
• Single case designs– ABA– ABAB– Multiple baseline design– Changing criterion design
Chapter 12Survey Research
• When to use survey research?• Primary survey designs– Cross-sectional, longitudinal
• Primary data collection methods– Questionnaires, interviews, web-based, paper-
based• Guidelines for evaluating (or creating) surveys• Sampling issues
Chapter 13Qualitative & Mixed Methods Research
• Definition of qualitative research• Nature of qualitative research– Vs. quantitative
• Validity in qualitative research– Types & strategies to improve– ways to reduce researcher bias
• Types of qualitative studies• Importance and types of triangulation
