Here is a collection of documents I use in my PSYC 2210

Measurement -- Scales of measurement, reliability, validity.
Scaling -- Thurstone,
Guttman, and Likert.
Correlation/Regression Analysis, t Tests, and ANOVA
An Introduction to Research Design
-- Experimental and nonexperimental designs, threats to internal and external validity, control of extraneous variables.
Pretest-Posttest Design With No Control Group
Randomized Experimental Design -- Random selection, random assignment, noise reduction.
Quasi-Experimental Design -- The treatment groups are not equated prior to manipulation of the independent variable.
MetaDesign -- Create and defend your own design.
Statistical Conclusion Validity -- An introduction to parametric inferential statistics.
Design and Analysis -- A quick review of the basics for commonly used tests of statistical significance.
Choice of NHST: Categorical versus Continuous Variables
Triangulation -- look at your research problem from multiple perspectives
