METASTATS: behavioral science statistics for Microsoft Windows and the HP49G programmable calculator.

METASTATS is an organized suite of approximately 150 programs designed for meta-analysis, power, effect sizes and their confidence intervals, significance test conversions, and other general statistics. This freeware works either on the HP49G calculator or preinstalled on a PC emulator under Windows. Many of the programs address gaps in commercially available software. The suite has a user-friendly interface: the screen prompts for input, and labels all output. Extensive documentation includes step-by-step examples, a fully annotated catalogue of the programs, and academic references for the formulas. Both versions of the programs (calculator and PC), documentation, and installation instructions are freely available from the author's Web site, http://www.netaxs.com/-efoster/.
