PSYC 2305, Spring 2022 Instructor: Tanya Smit PSYC 2305 Exam 2 Review Guide General information about the Exam: Due date : 11:59 pm on 3/11/22. o This means that your exam will automatically submit at 11:59 pm, even if you are still working on it. Time limit : 120 minutes (2 hours), unless you receive accommodations through Student Accessibility Center Questions: 50 multiple choice questions response questions o ~10 questions from each of the 5 chapters included in the test Respondus Lockdown browser : The lockdown browser and access to a webcam is required to take this exam. Please test your lockdown browser (see Browser Test (**Webcam**) - Requires Respondus LockDown Browser under “Assignments & Exams on Blackboard) before you take the test. If you run into issues testing the lockdown browser, please contact your instructor immediately so that we can resolve the issue. You will be able to see feedback on your exam (i.e., the correct answers to the questions) after the due date. Chapter 4: Fundamental Research Issues Define “validity” and know the 4 types of validity and what each one tells you. o Construct validity: the extent to which the measurement or manipulation of a variable accurately represents the theoretical variable studied. o Internal validity: the accuracy of conclusions drawn about cause and effect o External validity: the extent to which a study’s findings can be generalized to other populations and settings. *What is the difference between internal validity and external validity? o Statistical validity: Qualitative vs. Quantitative variables Operational definitions of variables: The set of procedures used when you measure or manipulate the variable Types of relationships between variables (positive linear, nonlinear, negative linear, curvilinear) • positive: increases in the values of one variable are accompanied by increases in the values of the second variable. • negative: increases in the values of one variable are accompanied by decreases in the values of the other variable. • curvilinear (nonmonotonic function) also called an inverted-U: increases in the values of one variable are accompanied by systematic increases and decreases in the values of the other variable. the direction of this relationship changes at least one. • no relationship: the graph is simply a flatline. Define correlation coefficient Experimental vs. non-experimental method • non-experimental: relationships are studied by observing variables of interest.
PSYC 2305, Spring 2022 Instructor: Tanya Smit — may be done by asking people to describe their behavior, directly observing their behavior, recording physiological responses, or examining various public school records such as census data. The variables vary together. • experimental: involves direct manipulation and control of variables. — the researcher manipulates the first variable of interest and then observes the response. The two variables do not vary together. the firs variable is introduced first to see its effect on the other variable. Dependent vs. independent variable o Which one is the “cause”? independent o Which one is the “effect”? depedent o Which one do you manipulate? independent o Which one do you observe based on the manipulation? dependent What are “participant variables”? Chapter 5: Measurement Concepts Define “reliability” and know the types of reliability and what each one tells you. o Test-retest reliability o Internal consistency reliability o Interrater reliability What is the difference between reliability and validity? What does each one tell you? How are measurement error and reliability related? What does it mean when a measure is reactive? Know the indicators of construct validity o Face validity o Content validity o Predictive validity o Concurrent validity o Convergent validity o Discriminant validity Types of measurement scales and how they differ o Nominal scales o Ordinal scales o Internal scales o Ratio scales Chapter 6: Observational Methods What is qualitative research? — Qualitative research focuses on people behaving in natural settings and describing their works in their own words What is quantitative research? —Quantitative research tends to focus on specific behaviors that can be easily quantified (e.g., counted).
PSYC 2305, Spring 2022 Instructor: Tanya Smit Define naturalistic observation/field observation: The researcher makes observation of individuals in their natural environments. Its used commonly in anthropology, animal behavior studies, and social sciences. o Is naturalistic observation primarily quantitative or qualitative? qualitative What is systematic observation? careful observation of one or more specific behaviors in a particular setting. o What is a coding system? o What is the possible role of reactivity in systematic observation? can be reduced with concealed presence and by allowing time for people to become accustomed to the observer and equipment. Define case studies and know the advantages of doing a case study. a observational method that provides a detailed description of an individual What is archival research? involves using previously compiled info to answer research questions. Know the three main types of archival research data: o Statistical records: collected by public and private organizations o Survey archives: consists of data and surveys that are stored digitally and available to researchers o Written and mass communication records: documents such as diaries, letters, ethnographies, public documents, discussion board messages, books, tweets, instagram or facebook post, magazine articles, television program and etc. What is content analysis in the context of archival research? Chapter 7: Asking People about Themselves (Survey Research) How are surveys useful? Know the potential issues with survey research. o Response set o Social desirability Know the three general types of survey questions o Facts and demographic (participant variables) o Behaviors o Attitudes and beliefs Know the basics of how to word questions on surveys. o Relatively simple questions o Avoid double-barreled questions o Avoid loaded questions o Avoid phrasing questions with negatives What are “yea-saying” and “nay-saying”? What issues do these response tendencies raise in survey research? Define close-ended and open-ended questions. What are the advantages of each? Know the pros and cons of using questionnaires in research. Know the pros and cons of using interviews in research.

PSYC 2305, Spring 2022 Instructor: Tanya Smit Define population and sample (know the difference between the two). Define confidence interval and know how to interpret a confidence interval. What is sampling error? Define probability sampling and know the three types of probability sampling (bolded = most important to know) o Simple random sampling o Stratified random sampling o Cluster sampling Define nonprobability sampling and know the three types of nonprobability sampling (bolded = most important to know) o Convenience sampling o Purposive sampling o Quota sampling Define sampling frame. Define response rate. Chapter 8: Experimental Design What is a confounding variable? What issues do confounding variables raise in experimental studies? How do confounding variables influence the internal validity of a study? Know the difference between posttest-only and pretest-posttest design. What are the pros and cons of each? Define retention and attrition. What are the differences between independent groups design and repeated measures design? o Note: independent groups design is the same thing as “between-subjects design”; repeated measures design is the same thing as “within-subjects design” What is counterbalancing? Why is it important in repeated measures designs? When do researchers use Latin square counterbalancing? How is this useful? Define matched pairs design.
