Based on Cohen, Cohen, West, and Aiken's Applied Mulitiple Regression/Correlation Analysis for the Behavioral Sciences. Contains more theoretical detail and includes sample SPSS code.

Applied Linear Regression set 2 8/1/98 Based on Neter, Kutner, Nachtsheim, & Wasserman's Applied Linear Statistical Models. Contains more mathematical detail and includes sample SAS code.

Transforming and Restructuring Data
Also available: SPSS examples 5/14/01 Explains efficient ways of transforming data (including tips on getting normal distributions), as well as information about how to change the unit of analysis of a data set. Includes an overview of programming with arrays and loops in SPSS and SAS.

Meta-Analysis 7/31/09
Describes procedures for quantitatively summarizing the results from mulitple studies. Focuses on d and r effect sizes.

Psychological Research Methods 5/9/01 Based on a class taught by Jamie DeCoster at the Free University Amsterdam.

Scale Construction 6/5/00 Detailed notes on how to build and test a scale, including sections on validity and reliability analysis.

Using ANOVA to Examine Data from Groups and Dyads
Also available: HLM overheads
4/12/02 Uses a flowchart to explain how to determine analysis for data from groups and dyads. Includes a section on how to calculate the intraclass correlation coefficient.

Mediation Bibliography
4/12/06
Describes several important references related to testing mediation. Includes links to three mediation websites.

Factor Analysis

Also available: CFA fit statistics
8/1/98
A basic theoretical introduction to exploratory and confirmatory factor analysis.

Data Analysis in SPSS
2/21/04
Explains how to perform and interpret the output of a number of different analyses in SPSS, including ANOVA, MANOVA, regression, logistic regression, and factor analysis.

Excel for Researchers
12/28/05
An overview of Excel features from the perspective of a researcher. Includes sections on formulas, importing and exporting files, and the Analysis Toolpak.

Restructuring Data from Computerized Experiments
12/29/05
Explains how to use SPSS's Data Restructure procedure to easily transform data in univariate format (where each line corresponds to a trial) to multivariate format (where each line correspons to a subject).
