Exam 3 Review Sheet

Note: This exam will strongly test your ability to apply the following concepts in hypothetical research situations and examples. Thus, while knowing the basic definitions will be important, it won’t be enough to do well on the exam.

Complex Designs  Complex design  Factorial design  Interpretation of design statements (e.g., how many IVs are there in a 2  4  3 design?)  Mixed design  Reasons for using a complex design (3 were given)  Interaction  Main effect  Simple main effect  Simple comparison  Relevant independent variable (from lecture)  Ceiling and floor effects (from lecture)  Interpretation of main effects and interactions in Figures and Tables  How to examine main effects in designs with 3 independent variables  Number and type of interactions in designs with 3 independent variables

Quasi-Experimental Designs  Basic vs. applied research  Types of quasi-experimental designs (QEDs) or “patched up designs” (see pp. 225-235)  One group (posttest only) design  One group pretest-posttest design  Posttest-only design with nonequivalent groups  Pretest-posttest design with nonequivalent groups  Time series designs  Simple interrupted time series design  Time series with non-equivalent control group design

 Types of confounds/threats to internal validity in QEDs (See pp. 121-130)  History  Maturation  Testing effects  Instrumentation (from lecture)  Regression to the mean  Experimental mortality/attrition  Hawthorne effect

 For each of the Quasi-experimental designs above, know which confounds interfere with the interpretation of the results  Stages of program evaluation (from lecture)

Single-Case Research Designs (almost all of this comes from lecture)  Case study method (see pp. 145-153)  Advantages (6) and disadvantages (4) of case studies  Nomothetic vs. ideographic approach  Types of single-case experimental designs  Baseline stage  ABAB design  Multiple baseline design (across individuals, across behaviors, across situations)

Unobtrusive Measures (most of this comes from lecture)  Reactivity/person reaction bias and unobtrusive measures (see pp. 130-top of134)  Types of Unobtrusive measures  Physical traces  Accretion vs. erosion measures  Natural vs. controlled measures

 Archival data (see pp. 166-170)

 Problems in the use of archival data  Selective deposit  Selective survival
