helpful statistics resources
- Karl Wuensch's Statistics Lessons: Dr. Wuensch offers a rich trove of statistical educational materials, data sets, and practice opportunities. There is a textbook worth of material on experimental design, univariate statistics, and multivariate statistics. Thousands of students have benefited from his gift for blending technical detail, practical application, and humor in a comprehensible manner. Please read his fair usage page before downloads.
- Statsoft: The Electronic Statistics Textbook begins with an overview of the relevant elementary (pivotal) concepts and continues with a more in depth exploration of specific areas of statistics, organized by "modules" and accessible by buttons, representing classes of analytic techniques. A glossary of statistical terms and a list of references for further study are included. It is helpful as a generic reference and review of relevant techniques.
- Jeremy Anglim: While less active now than in the past, Dr. Anglim has a great page with +100 posts on writing, programming, and using both R and SPSS. The best part is Dr. Anglim has a background in Industrial and Organizational Psychology. As a result, all his posts are geared towards common psychology data issues and problems. It has proven very insightful in helping consolidate ideas or implementing a certain technique in R (e.g., cluster analysis).
- David Kenny's Webpage: A giant in the field of psychology, David Kenny is behind many innovative methodological advancements in social psychology (i.e., mediation, lagged analyses, dyadic data modeling, bias and accuracy). His webpage does not disappoint. It includes short yet informative overviews of many complex ideas on social perception, model fit, structural equation modeling, mediation versus moderation, and dyadic data modeling. There are also many tutorials and links to other informative pages on related topics.
- The Analysis Factor: The Analysis Factor offers statistical consulting, resources, and training that researchers need to conduct quality work. Their aim is to be accessible, understandable, and affordable. Karen Kelly, the owner, is a pro at translating complex statistics into intuitive descriptions of their aim and purpose.
- Reproducing Results and P-Hacking: A very important discussion of the difficulty and subjectivity of choices made in studying phenomena in social science (from psychology to political science). This blog also provides many interactive graphs to help illustrate how slightly changing the definition of an outcome can result in varying levels of statistical significance.
- StatsTools: Dr. Buchanan provides many resources and YouTube channel videos containing hours of tutorials on how to complete statistical procedures in SPSS, Excel, R, MOTE, and G*Power. This information is used as teaching material in Dr. Buchanan’s courses and is open access for students/researchers to use as needed.
