TXM is a free, open source text corpus analysis environment. Its features include concordance, collocate search, frequencies based on the CQP full text search engine and statistical functions based on R packages. It can export results in CSV, XML or SVG format, and runs as a standalone desktop application in Windows, OS X and Linux environments, or as a web portal (download the leaflet for more).

R is an open source programing language designed for statistical analysis and parallel computing. R began its life as a research project at the University of Aukland, but has since expanded to become a collaborativly run open source project run by the GNU. R has libraries for data import, regular expression data splitting, and visualization of data. R can be run as either a script or as a working environment.

Dataplot is a free software system for data analysis, including characterization, visualization and modelling. It was developed in FORTRAN 77, and has been in continuous development since 1978. Dataplot is well-documented, with numerous tutorials for using and extending it. In addiiton, over 30 graphic types are supported, such as histograms, box plots, scatter plots and normal probability plots. This tool is currently available in Unix, Linux, OS X and Windows versions. Dataplot is open source, but is trademarked rather than licensed.

Weft QDA is a free and open-source tool for the analysis of textual data. You may import documents from plain text or PDF, apply character-level coding, category and document memos, retrieve coded text, apply simple coding statistics, apply free-text search, and export to HTML and CSV formats.

RStudio is an integrated development environment (IDE) for R. It is available in both open source and consumer versions, and can run either on your desktop, or through a browser connected to RStudio Server. Features include syntax highlighting, code completion, smart indentation, and an interactive debugger.

A website that explains statistical concepts and provides a web-based environment for performing those calculations. Tools include a graph maker, distribution generators, t-tests and procedures, and correlation and regression tests. All tools have been written in Javascript and run within the browser.

Statistical Lab is a graphical user interface designed to make statistical analysis easier to understand. This interactive tool will connect and display data frames, frequency tables, random numbers or matrixes. Statistical Lab uses R to run calculations, conduct analyses and perform multiple simulations and manipulations.

StatCrunch is web-based statistical analysis and data-sharing software.

Rwui allows you to convert an R script to a web page with an interface where users can run the script(s) even if they don't know R.

Minitab provides tools for statistical analysis and visualization. It includes tools for creating graphics, and working with variance, regression, reliability, sample size, time series, forecasting, equivalence tests, tables, simulations, and distributions.
