This program, developed at the University of Michigan, is for use with Windows and provides comprehensive statistical and data management package for survey analysis. It can support moderate to large data sets.
OpenEpi provides statistics for counts and measurements in descriptive and analytic studies, stratified analysis with exact confidence limits, matched pair and person-time analysis, sample size and power calculations, random numbers, sensitivity, specificity and other evaluation statistics, R x C tables, chi-square for dose-response, and links to other useful sites.
A free replacement for SPSS (although at this time it implements only a small fraction of SPSS's analyses). But it's free, and will never "expire". It replicates the "look and feel" of SPSS very closely, and even reads native SPSS syntax and files!
SalStat is an application design for the analysis of scientific data: the kind of data commonly seen in psychology, for example. It can perform a range of tests already from descriptive statistics through to analysis of variance tests and their nonparametric equivalents.
