1 UNIT 1: Fundamentals of research design and s Reading Assignment: Aron Reading on website: Logic & Language of Psychology Research 1. What are the goals of science and how do the types of statistics relate to those goals. 2. Explain what is meant by a and consider the role of reliability and validity in in research. 3. Explain the role of descriptive research, with emphasis on appropriate conclusions from descriptive data. 4. Recognize correlational research and identify alternate hypotheses to explain a relationship found in a correlational study. 5. Use the concepts of independent and dependent in describing experimental research and designing simple studies. Distinguish between the true experiment and a quasiexperiment. 6. Discuss the importance of randomization in the selection of subjects and assignment of subjects to groups in experiments; considering the advantages of experiments over quasi-experiments? Terms Reliability Validity Correlational design True experiment Manipulation Experimental group Control group Independent Dependent Tutorial Examples 1. Flat Tire Modeling 2. Humor study 3. Newspaper examples 4. Marriage & health 5. Heart Rate study 6. Room Color study 7. Self-efficacy study Extraneous s Operational Definition Population Sample Random sampling Random assignment Quasiexperimental Repeated measures Counterbalancing Scan to download mp4 videos to your smart phone.

Describe Understand Predict Control Fundamentals of research design and s Prediction makes the theory Testable Descriptive statistics Associated Statistics Summarize and organize data Inferential statistics Eliminate the hypothesis the relationships between s occur by chance make inferences that go beyond the scores from a research study; predict Variables: Vary and can be assigned a number Reliability consistency Validity Reflect the construct or labeled behavior
3 Theory and the Scientific Method Research Designs Multiple studies lead to conclusions Theory Evaluate relative to other theory and research Hypothesis Hypothesis Testing Research Multiple Working Hypotheses Descriptive Correlational Quasi experimental Experimental Multiple studies lead to conclusions Descriptive Research Data Collection methods Observation Survey Data Archival Data Clinical Interview When a student changes an answer on a test, it is most likely that they will change the answer from; A. wrong to right. B. wrong to wrong. C. right to wrong. D. each equally to each of the three.

Operational Definitions of Variables: Are they valid? TV violence Independent Dependent Operational Definitions: The method by which a is translated into numbers in a research study Extraneous s: Variables which vary other than the I.V. and D.V. Aggression Validity: Are there extraneous s confounded with the I.V. or D.V.? Experimental Group TV limited to less violent programming. Sometimes called treatment group Control Group Allowed to watch all programming no matter how violent Feshback
