This page lists primarily statistical software, along with mapping, spreadsheets, database, stuff to do data analysis or management.  All of the packages are free to use, that is: there is no charge for individuals to use them. Many of the websites say that individuals are free to download and use the packages. In some cases, there may be charges to institutions. Some of the packages are also open, that is, they are free to use and the source code is freely available so anyone can make modifications to the programs if they wish to.  At the bottom of this page, I list a few sites that have information about what "free" means.

Please note: I've only used a few of these software programs a little bit, so I can't say much about how good they are, whether they crash, have viruses, or much else about them.  If you use them, please let me know how well they work.  If there are any major problems, I'll take them off this list.  I'm sorry to add the usual disclaimer that, while I don't expect any problems with them, if you use any of these, I can't be responsible for any problems that may occur. Also, I'm not necessarily recommending any, just providing info and links.


There are many free statistical programs. See this article  at Citizendium about free statistical software.

Several of these stat programs were reviewed in an article in Opus 12, a journal covering Opus 12 Foundation research. Stawicki SPA. Guide to free statistical software: General applications. OPUS 12 Scientist 2010;4(1):12-13.    Reviewed OpenStat, Sofa, PSPP, MicrOsiris and a few others. Just describes the programs.
  Ratings of free statistical software  
Top rated are SAS, PSPP, Develve, and a couple of others that aren't really general statistical software. There isn't a date for this review.               
  This isn't a review of the packages, but a look at which ones are popular, not limited to free ones   The Popularity of Data Analysis Software, by Robert A. Muenchen
  Also look at this, the most popular response,   by Robert Thomas Brennan · Harvard University, explaining some of the difficulties in answering which is the most popular. For example, excel has a lot of statistical functions, but isn't thought of as statistical software so may not be counted

Other lists of free stat software

Free statistical software  The First and MAIN list of software.  I got links to several of the stat packages listed here from this site, which lists more info about each package. This statpages site was started and maintained for many years by John Pezzullo. Sadly, Mr. Pezzullo passed away in June 2016. I believe the site is now maintained by a couple of people, including Søren Merser. Statpages is a great site to bookmark.
StatSci list of free software   also lists some of the above.

R is a very widely used program, with tons of documentation
R: The Comprehensive R Archive Network   "R, also known as "GNU S", is a language and environment for statistical computing and graphics."  It is, I understand, like S+, a statistical language.  R is better for graphics than SAS.  However, R is complex, and takes a lot of study, so only use this if you have complex statistical or graphical needs.  If this site doesn't work, try   in the US.

There are many graphical interfaces.  Several are reviewed here   
Picking a gui interface for R. February 3, 2014.  
this June 2012 issue of Journal of Statistical Software also reviews several of the GUIs     
Here is a poll on which GUIs are most used   (R Studio was the top, out of  562 votes).
