Meta-Analysis
Homepage

Meta-analysis is a long established method of mathematically summarizing research results. It is a developing field and we are improving our techniques constantly. There are several comprehensive research websites that review the details of meta-analysis and we report them below. In addition, some of our results and our own techniques of meta-analysis are discussed here.

There are a few meta-analyses that are being conducted and that have already been completed. Here are copies of some of the publications

This is an Excel spreadsheet that summarizes the personality of nations used in the following study:

Steel, P., & Ones, D. (2002). Personality and Happiness: A National Level of Analysis. Journal of Personality and Social Psychology, 83(3), 767-781.

This is the latest version of the meta-analysis that was reported in the August 5th, 2003 conference Counseling the Procrastinator in Academic Settings. It is perpetually under review at one journal or another.

This runs in Microsoft Excel and incorporates many of the latest insights into meta-analysis (e.g., (K-1)/K adjustment, the IHVI - Bayesian Estimation - technique). The code is open and you are free to make any updates to it. The idea behind open-code programs is that we all share our experience and we create a free platform that is superior to those commercially available. Since this will always be a work in progress, it is distributed "as is," recognizing that there is always the possibility of software bugs. There are no identified problems with the present version.

This is free software for coding studies directly into a flat file. It also runs in Microsoft Excel. It has a variety of built-in error checkers and cuts down coding time by as much as 75%.  It is based on coding a correlation-based meta-analysis, which limits its use for treatment or experimental-based analyses. If you make of use of this and update it, please forward a copy of your revised version.
