OpenStat -- a
general stats package for Win 95/98/NT, developed by Bill Miller of Iowa
State U, with a very broad range of data manipulation and analysis
capabilities and an SPSS-like user interface. Bill also has provided an excellent
downloadable
textbook in the form of Adobe Acrobat files.
SOFA (Statistics Open
For All) -- an innovative statistics, analysis, and reporting program. Available
for Windows, Mac and Linux systems. Has an emphasis on ease of use, learn
as you go, and beautiful output. Check out
list of features.
ViSta -- a Visual Statistics
program for Win3.1, Win 95/NT, Mac and Unix, featuring a Structured Desktop,
with features designed to structure and assist the statistical analyst.
PSPP -- 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! Some other features...

• 
  Supports over 1 billion cases and over 1 billion variables.
  
• 
  Choice of terminal or graphical user interface; Choice of text, postscript
  or html output formats.
  
• 
  Inter-operates with Gnumeric, OpenOffice.Org and other free software.
  
• 
  Easy data import from spreadsheets, text files and database sources.
  
• 
  Fast statistical procedures, even on very large data sets.
  
• 
  No license fees; no expiration period; no unethical “end user license
  agreements”.
  
• 
  Fully indexed user manual.
  
• 
  Cross platform; Runs on many different computers and many different operating
  systems.

OpenEpi Version 2.3 -- OpenEpi is a
free, web-based, open source, operating-system-independent series of programs
for use in public health and medicine, providing a number of epidemiologic
and statistical tools. Version 2 (4/25/2007) has a new interface that presents
results without using pop-up windows, and has better installation methods
so that it can be run without an internet connection. Version 2.2 (2007/11/09)
lets users run the software in English, French, Spanish, or Italian.
Statext -- Provides a nice
assortment of basic statistical tests, with text output (and text-based
graphics). Capabilities include: rearrange, transpose, tabulate and count
data; random sample; basic descriptives; text-plots for dot, box-and-whiskers,
stem-and-leaf, histogram, scatterplot; find z-values, confidence interval
for means, t-tests (one and two group, and paired; one- and two-way ANOVA;
Pearson, Spearman and Kendall correlation; ;inear regression, Chi-square
goodness-of-fit test and independence tests; sign test, Mann-Whitney U and
Kruskal-Wallis H tests, probability tables (z, t, Chi-square, F, U); random
number generator; Central Limit Theorem, Chi-square distribution.
MicrOsiris -- a comprehensive
statistical and data management package for Windows, derived from the OSIRIS
IV package developed at the University of Michigan. It was developed for
serious survey analysis using moderate to large data sets. Main
features: handles any size data set; has Excel data entry; imports/exports
SPSS, SAS, and Stats datasets; reads ICPSR (OSIRIS) and UNESCO (IDAMS) datasets;
data mining techniques for market analysis (SEARCH --very fast for large
datasets); interactive decision tree for selecting appropriate tests; database
maniuplation (dictionaries, sorting, merging, consistency checking, recoding,
transforming) extensive statistics (univariate, staccerplot, cross-tabs,
ANOVA/MANOVA, log-linear, correlation/regressionMCA, MNA, binary segmentation,
cluster, factor, MINISSA, item analysis, survival analysis, internal
consistency); online, web-enabled users manual; requires only 6MB RAM; uses
12MB disk, including manual. Fully-functional version is free; the authors
would appreciate a small donation to support ongoing development and
distribution.
Gnumeric -- a high-powered
spreadsheet with better statistical features than Excel. Has 60 extra functions,
basic support for financial derivatives (Black Scholes) and telecommunication
engineering, advanced statistical analysis, extensive random number generation,
linear and non-linear solvers, implicit intersection, implicit iteration,
goal seek, and Monte Carlo simulation tools.
Statist -- a compact,
portable program that provides most basic statistical capabilities: data
manipulation (recoding, transforming, selecting), descriptive stats (including
histograms, box&whisker plots), correlation & regression, and the
common significance tests (chi-square, t-test, etc.). Written in C (source
available); runs on Unix/Linux, Windows, Mac, among others.
Tanagra
-- a free (open-source) data-mining package, which supports the standard
"stream diagram" paradigm used by most data-mining systems. Contains components
for Data source (tab-delimited text), Visualization (grid, scatterplots),
Descriptive statistics (cross-tab, ANOVA, correlation), Instance selection
(sampling, stratified), Feature selection and construction, Regression (multiple
linear), Factorial analysis (principal components, multiple correspondence),
Clustering (kMeans, SOM, LVQ, HAC), Supervised learning (logistic regr.,
k-NN, multi-layer perceptron, prototype-NN, ID3, discriminant analysis, naive
Bayes, radial basis function), Meta-spv learning (instance Spv, arcing, boosting,
bagging), Learning assessment (train-test, cross-validation), and Association
(Agrawal a-priori). (French-language page

Dap -- a statistics
and graphics package developed by Susan Bassein for Unix and Linux systems,
with commonly-needed data management, analysis, and graphics (univariate
statistics, correlations and regression, ANOVA, categorical data analysis,
logistic regression, and nonparametric analyses). Provides some of the core
functionality of SAS, and is able to read and run many (but not all)
SAS program files. Dap is freely distributed under a GNU-style "copyleft".

PAST -- an easy-to-use data
analysis package aimed at paleontology including a large selection
of common statistical, plotting and modelling functions: a spreadsheet-type
data entry form, graphing, curve fitting, significance tests (F, t, permutation
t, Chi-squared w. permutation test, Kolmogorov-Smirnov, Mann-Whitney,
Shapiro-Wilk, Spearman's Rho and Kendall's Tau tests, correlation, covariance,
contingency tables, one-way ANOVA, Kruskal-Wallis test), diversity and similarity
indices & profiles, abundance model fitting, multivariate statistics,
time series analysis, geometrical analysis, parsimony analysis (cladistics),
and biostratigraphy
