   9.7overall

   R is a free language and environment for statistics and graphics; RStudio is Posit's free open source IDE for working in it.

   Best forStudents and researchers who want the most complete free toolkit and are willing to write code.

   Adoption data

   Millions weeklyPosit, which builds RStudio and the tidyverse, says its 350+ open source packages are used by millions of people every week.

   Posit, RStudio IDE (2026): “We build RStudio, the tidyverse, Shiny, Quarto, and 350+ packages used by millions of people every week.”

   R is the most complete free option for statistics. The R Project describes it as a free software environment for statistical computing and graphics that runs on UNIX platforms, Windows and macOS, and the CRAN repository currently lists 25,700 contributed packages, organized into 50 Task Views by topic. That breadth means mixed models, survival analysis, Bayesian methods and survey weights are all a package install away. RStudio, built by Posit, adds the console, a syntax-highlighting editor, plot and history panes, debugging tools and Quarto integration for reports, and Posit says RStudio will remain free. The cost is the learning curve: everything starts from code, and quality varies between community packages, so check the documentation and citations of anything you rely on. For a thesis or a research career, though, scripts give you a reproducible record of every step, and the skills carry over to almost any lab or employer.

   Strengths

   • +Costs nothing, including the RStudio IDE
   • +Almost any statistical method is available as a package
   • +Scripts make every analysis reproducible

   Limitations

   • −You have to learn to write code
   • −Package quality varies because anyone can contribute
   • −No vendor support desk for the free edition

   SummaryR with RStudio is the best free statistical software if you can invest a few weeks in learning code. Nothing else here matches its range of methods at no cost.

   JASP

   A free, open source point-and-click statistics program from the University of Amsterdam with classical and Bayesian analyses.

   8.9overall

   A free, open source point-and-click statistics program from the University of Amsterdam with classical and Bayesian analyses.

   Best forPsychology and social science students who want menus instead of code and Bayesian tests side by side.

   Adoption data

   Top-cited R GUIIn Robert Muenchen's count of scholarly articles that cite statistics software, JASP and jamovi lead every other graphical front end to R.

   Robert A. Muenchen, r4stats.com, The Popularity of Data Science Software (2022): “JASP and jamovi are both front-ends to the R language and are way out front in this category.”

   JASP is the friendliest free choice for students who would rather click than code. It is an open source project supported by the University of Amsterdam, and its main idea is that every standard procedure comes in both a frequentist and a Bayesian form, so you can report a p-value and a Bayes factor from the same menu. The interface is a spreadsheet with drag-and-drop variable selection, results update as you change options, and output is annotated to explain what each table means. Tables and graphs copy into Word in APA format, which saves time on psychology and social science papers, and the Open Science Framework integration helps with sharing. The limits show on bigger projects: data cleaning tools are thin compared with SPSS, and specialized models still need R or Stata. In Robert Muenchen's tracking of scholarly citations, JASP and jamovi lead all other graphical front ends to R.

   Strengths

   • +Free with no license limits
   • +Bayesian tests sit next to classic tests in the same menus
   • +Copies APA-style tables straight into Word

   Limitations

   • −Fewer advanced models than R, Stata or SAS
   • −Limited data management compared with SPSS
   • −Scripting is not its main workflow

   SummaryJASP is the best free point-and-click option for psychology and social science courses, especially if you want Bayesian results. Move to R when your models outgrow its menus.

3. 3

   jamovi

   A free, open statistical spreadsheet built on R, available as a desktop app or in the cloud.

   8.8overall

   A free, open statistical spreadsheet built on R, available as a desktop app or in the cloud.

   Best forStudents and teachers who want an SPSS-style spreadsheet that is free and can show the R code behind it.

   Adoption data

   5M+ downloadsjamovi reports more than 5 million downloads and use at more than 300 universities.

   jamovi, jamovi: open statistical software for the desktop and cloud (2026): “Used by researchers, educators, and students worldwide. 5M+ Downloads 300+ Universities”

   jamovi calls itself a free and open statistical spreadsheet and pitches itself as an alternative to costly proprietary stats products. You drag variables into place, set options, and results update immediately, with no code required, while R does the computing underneath. The desktop version is always free and the cloud Guest plan runs in a browser with no install or credit card, which helps on locked-down lab or school computers. The jamovi library adds 70+ modules for methods beyond the core menus. jamovi reports more than 5 million downloads and use at more than 300 universities, and it shares the lead with JASP in citations of R front ends. Against JASP it is less focused on Bayesian statistics and more on a general spreadsheet workflow. Against SPSS it covers the methods taught in most undergraduate courses but not the full catalog of procedures and add-ons, so specialist work may still need R.

   Strengths

   • +Free on desktop forever, with a free cloud tier
   • +Familiar spreadsheet layout for SPSS users
   • +Add-on modules extend the menus

   Limitations

   • −Fewer built-in procedures than commercial suites
   • −Large datasets are better handled in R or Stata
   • −Some modules come from the community rather than the core team

   Summaryjamovi is the easiest free switch for SPSS users and suits intro statistics courses. Its cloud tier makes it the simplest option to run on shared machines.

4. 4

   Stata

   StataCorp's integrated package for data management, statistics, graphics and reporting, widely used in economics and public health.

   8.6overall

   StataCorp's integrated package for data management, statistics, graphics and reporting, widely used in economics and public health.

   Best forEconomists, epidemiologists and policy researchers who want a reliable command language with long-term reproducibility.

   Adoption data

   180+ countriesStataCorp says Stata is distributed in more than 180 countries.

   StataCorp, Why use Stata (2026): “Stata is distributed in more than 180 countries.”

   Stata is the paid package many economists, epidemiologists and policy researchers learn in graduate school. StataCorp describes it as a complete, integrated package for data manipulation, visualization, statistics and automated reporting. Its standout trait is integrated versioning: StataCorp says a script written in 1985 will still run and produce the same results today, which matters for replication files. Documentation runs to over 19,000 pages in 36 volumes and is searchable with the help command. Student pricing is reasonable: Stata/BE costs $48 for six months, $94 per year or $298 perpetual, and six-month and annual licenses include StataNow feature updates. Larger datasets need Stata/SE or the multicore Stata/MP, which cost more. The main drawback against R is cost and a smaller library of cutting-edge methods, though community-contributed commands fill many gaps.

   Strengths

   • +Student licenses are cheap compared with other commercial suites
   • +Scripts written decades ago still run with the same results
   • +Documentation is detailed and searchable from inside Stata

   Limitations

   • −Paid license for every user
   • −Student pricing requires academic eligibility
   • −Faster editions cost more

   SummaryStata is the best paid choice for economics, public health and policy research, and its student licenses are affordable. Pick it when your field's replication files are written in Stata.

   IBM SPSS Statistics

   IBM's long-running menu-driven statistics package for regression, factor and cluster analysis, forecasting and custom tables.

   8.5overall

   IBM's long-running menu-driven statistics package for regression, factor and cluster analysis, forecasting and custom tables.

   Best forSocial science, nursing and business students whose courses or employers standardize on SPSS.

   Adoption data

   Most-citedIn Robert Muenchen's analysis of Google Scholar articles that mention data science software, SPSS is the most cited package, as it has been for over 20 years.

   Robert A. Muenchen, r4stats.com, The Popularity of Data Science Software (2022): “SPSS is the most popular package, as it has been for over 20 years.”

   SPSS Statistics is the package most social science and nursing students meet first, and Robert Muenchen's count of Google Scholar articles shows it has been the most cited statistics package for over 20 years. IBM sells it as a base subscription starting at $99 per authorized user, covering core statistics, data preparation and bootstrapping, with add-ons from $79 for custom tables and advanced statistics, forecasting and decision trees, or complex samples and missing values. IBM's page notes that prices are indicative and vary by country, and it also sells perpetual licenses. The appeal is breadth through menus: generalized linear models, mixed models, factor and cluster analysis are a few clicks away. The drawbacks are cost and fragmentation, since methods many students need sit in paid add-ons. Before buying, check whether your university licenses it, and consider PSPP, JASP or jamovi if you only need the basics.

   Strengths

   • +Menus cover nearly every method taught in social science courses
   • +Most cited statistics package in scholarly articles
   • +Many universities already license it for students

   Limitations

   • −Base subscription starts at $99 per user and advanced methods are add-ons
   • −Prices shown on IBM's page vary by country
   • −Less flexible than code-based tools for custom methods

   SummarySPSS is the right buy when a course, supervisor or employer expects SPSS output. Otherwise a free alternative covers most coursework.

6. 6

   SAS

   Enterprise analytics software with a free cloud edition, SAS OnDemand for Academics, for teaching and learning.

   8.3overall

   Enterprise analytics software with a free cloud edition, SAS OnDemand for Academics, for teaching and learning.

   Best forBiostatistics, pharma and banking students preparing for employers that run SAS.

   Adoption data

   150+ countriesSAS reports customers in more than 150 countries.

   SAS Institute, SAS company information (2026): “150+ countries with SAS customers”

   SAS is the enterprise statistics system behind much clinical trial, insurance and banking analysis, and students can use it at no cost. SAS describes OnDemand for Academics as a free, cloud-based learning environment for teaching and learning analytics, and students, educators and independent learners can use SAS Studio in a browser to write SAS programs. Instructors can share a link with no gating, and Enterprise Guide is available after registration. The free edition is meant for learning, so commercial projects need a licensed SAS Viya deployment, priced by quote. SAS reports customers in more than 150 countries, and it is a long-standing tool in industries such as pharmaceuticals and banking. For academic research outside those fields, R and Stata are free or cheaper to keep using after graduation, since the free edition ends with your learning use. Choose SAS if your target industry runs on it; otherwise its free academic edition is a low-risk way to try it.

   Strengths

   • +Free for students, educators and independent learners
   • +Runs in a browser, so no installation
   • +Same SAS language used in commercial SAS deployments

   Limitations

   • −Commercial pricing is quote-only
   • −Free edition is for teaching and learning, not commercial work
   • −SAS language is less common in new academic research than R

   SummarySAS is worth learning for students heading into pharma, insurance or banking, and the academic edition costs nothing. Others will get more from R or Stata.

   GraphPad Prism

   Statistics and scientific graphing software built for lab scientists, strong on curve fitting and publication figures.

   8.2overall

   Statistics and scientific graphing software built for lab scientists, strong on curve fitting and publication figures.

   Best forBiology and biomedical researchers who need common lab statistics and publication-quality graphs.

   Adoption data

   750,000+ scientistsGraphPad says more than 750,000 scientists in 110 countries rely on Prism.

   GraphPad (Dotmatics), GraphPad Prism (2026): “More than 750,000 scientists in 110 countries rely on Prism to help share their research with the world.”

   GraphPad Prism is the default analysis tool in many biology labs, because it combines common statistics with graphs that look ready for a journal. GraphPad says more than 750,000 scientists in 110 countries rely on it. GraphPad positions it as the only easy to use nonlinear regression software in a customer quote on its homepage, and curve fitting is where it is strongest for bench scientists who are not statisticians. The Standard plan covers statistical analysis, graphing and Prism Cloud, while Pro adds multiple-variable analyses, k-means and hierarchical clustering, confidence ellipses and multifactor ANOVA. Students pay $142 per year for Standard or $213 for Pro, monthly plans start at $50, and a personal academic Standard subscription is $265 per year. Perpetual licenses exist, but GraphPad itself discourages them because they include no upgrades. Prism is not a general-purpose statistics system: survey analysis, complex multilevel models and large datasets belong in R, Stata or SAS.

   Strengths

   • +Graphs are ready for journals with little editing
   • +Strong nonlinear regression and curve fitting
   • +Short-term monthly plans for one project

   Limitations

   • −Subscription for every user
   • −Narrower range of methods than R, SAS or Stata
   • −Pro features cost extra

   SummaryPrism is the best pick for lab scientists who need correct common tests and clean figures quickly. Data-heavy research still calls for a full statistics package.

   JMP

   Interactive data analysis software from JMP Statistical Discovery for scientists and engineers, with a free Student Edition.

   7.9overall

   Interactive data analysis software from JMP Statistical Discovery for scientists and engineers, with a free Student Edition.

   Best forEngineering and science students who want visual, menu-driven analysis and design of experiments.

   Adoption data

   Hundreds of thousandsJMP says hundreds of thousands of scientists and engineers choose its software.

   JMP Statistical Discovery, JMP statistical discovery software (2026): “Why hundreds of thousands of scientists and engineers choose JMP”

   JMP is the visual, point-and-click statistics package that engineers and industrial scientists tend to prefer. Its core product covers design of experiments, regression and statistical modeling, with interactive dashboards where selecting points in one graph highlights them everywhere else. JMP Pro adds model screening, cross-validation, mixed models, functional data analysis and Bayesian optimization, and JMP Clinical targets clinical trial review. For students the key fact is the JMP Student Edition, which JMP says is free for qualified students, instructors and academic researchers at degree-granting institutions and renews at no cost every 12 months while you stay eligible. Paid subscriptions include support, but we could not confirm a USD price from this location, so check JMP's buy page. JMP says hundreds of thousands of scientists and engineers use it. It is less common than SPSS, R or Stata in social science research, so match it to your field before committing.

   Strengths

   • +Free Student Edition, renewable every 12 months while eligible
   • +Linked graphs make exploring data fast
   • +Strong design of experiments tools

   Limitations

   • −Paid license prices were not confirmed in USD here
   • −Student Edition is limited to students and educators at degree-granting institutions
   • −Smaller academic citation base than SPSS or R

   SummaryJMP is a strong choice for engineering, quality and science courses, and the Student Edition removes the cost for students. Social science students will find more support for SPSS, R or Stata.

   Minitab Statistical Software

   Statistics software for quality and process improvement, popular in Six Sigma training and manufacturing.

   7.5overall

   Statistics software for quality and process improvement, popular in Six Sigma training and manufacturing.

   Best forStudents and professionals in quality engineering, Six Sigma and process improvement.

   Adoption data

   90% of Fortune 100Minitab says its customer list includes over 90% of the Fortune 100 and the majority of the Fortune 500.

   Minitab, About Minitab (2026): “Our customer list features over 90% of the Fortune 100 and the majority of the Fortune 500.”

   Minitab is the statistics package of quality engineering. Minitab presents its Statistical Software as built for quality and process improvement, with control charts, capability analysis and design of experiments, and it recently added advanced design of experiments. That focus is why it appears in Six Sigma courses and manufacturing plants, and Minitab says over 90% of the Fortune 100 are customers. For general research it is a narrower fit: the menus favor industrial questions over survey weighting, multilevel models or Bayesian analysis. Pricing is not published on the US pricing page, which asks you to fill out a form, so we mark the price as pending; a free trial of select products is available. Students should check whether their program provides Minitab or the Education Hub, since buying a license yourself is rarely needed for coursework. If your interest is research statistics rather than process control, the free tools higher on this list cover more ground.

   Strengths

   • +Menus map closely to Six Sigma and quality courses
   • +Widely used in large manufacturers
   • +Free trial before buying

   Limitations

   • −Pricing is by inquiry form on the US site
   • −Less suited to social science or biomedical research
   • −No free edition

   SummaryMinitab is the right tool for quality engineering and Six Sigma work. For academic research, R, JASP or Stata cover more methods for less money.

    GNU PSPP

    A free GNU program for statistical analysis of sampled data, designed as a replacement for SPSS.

    7.2overall

    A free GNU program for statistical analysis of sampled data, designed as a replacement for SPSS.

    Best forStudents who need SPSS-style syntax and menus for basic analyses at no cost.

    PSPP is the free answer to a common student problem: a course taught in SPSS and no license at home. The GNU Project describes it as a program for statistical analysis of sampled data and a free replacement for SPSS that appears very similar to it, so menus and syntax will feel familiar. It covers descriptive statistics, t-tests, ANOVA, linear and logistic regression, measures of association, cluster analysis, reliability and factor analysis, which is enough for most introductory and many intermediate courses. GNU says accuracy is taken seriously, with regular manual testing and daily snapshot builds that run automatic regression tests. The trade-offs are scope and pace: PSPP lacks many of SPSS's advanced procedures and add-ons, it is maintained by a small volunteer team, and there is no published usage figure, so we score adoption conservatively. If you are not tied to SPSS conventions, jamovi or JASP offer more modern interfaces at the same price.

    Strengths

    • +Free with no license expiry
    • +Familiar for anyone trained on SPSS
    • +Source available to inspect and modify

    Limitations

    • −Covers far fewer procedures than SPSS
    • −Small volunteer maintainer team
    • −No published user or adoption figures

    SummaryPSPP is the best free stand-in when your course expects SPSS syntax and output. For anything beyond the basics, use jamovi, JASP or R.
