PSPP

This software provides a comprehensive set of capabilities including frequencies, cross-tabs comparison of means (t-tests and one-way ANOVA), linear regression, logistic regression, reliability (Cronbach's alpha, not failure or Weibull), and re-ordering data, non-parametric tests, factor analysis, cluster analysis, principal components analysis, chi-square analysis and more.

At the user's choice, statistical output and graphics are available in ASCII, PDF, PostScript, SVG or HTML formats. A range of statistical graphs can be produced, such as histograms, pie-charts, scree plots, and np-charts.

PSPP can import Gnumeric and OpenDocument spreadsheets, Postgres databases, comma-separated values and ASCII files. It can export files in the SPSS 'portable' and 'system' file formats and to ASCII files. Some of the libraries used by PSPP can be accessed programmatically; [http://search.cpan.org/~pdonelan/PSPP-Perl-0.7.2.20090730/lib/PSPP.pm PSPP-Perl] provides an interface to the libraries used by PSPP.

The PSPP project (originally called "Fiasco") was born at the end of the 1990s as a free software replacement for SPSS, which is a data management and analysis tool, at the time produced by SPSS Inc. The nature of SPSS's proprietary licensing and the presence of digital restrictions management motivated the author to write an alternative which later became functionally identical, but with permission for everyone to copy, modify and share.

In the book "SPSS For Dummies", the author discusses PSPP under the heading of "Ten Useful Things You Can Find on the Internet".{{cite book |url=http://media.wiley.com/product_data/excerpt/48/04701134/0470113448-2.pdf |title=SPSS Statistics for Dummies |isbn=978-1118989012 | first1=Keith |last1=McCormick |first2=Jesus |last2=Salcedo |first3=Aaron |last3=Poh|date=2 June 2015 |publisher=John Wiley & Sons }} Another review of free to use statistical software also finds that the statistical results from PSPP match statistical results for SAS, for frequencies, means, correlation and regression.{{cite web |last1=Shackman |first1=Gene |title=Free To Use Statistical Software: Comparing Statistical Analyses |date=10 May 2022 |url=https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4105959 |publisher=SSRN |ssrn=4105959 |access-date=16 June 2022}}

One study found that students who used PSPP became more positive about learning statistics while using PSPP.{{cite journal |last1=Tomas |first1=Minerva Sto |title=The Use of PSPP Software in Learning Statistics |journal=European Journal of Educational Research |date=2019 |volume=8 |issue=4 |pages=1127–1136 |doi=10.12973/eu-jer.8.4.1127 |s2cid=242113359 |url=https://eric.ed.gov/?id=EJ1231626|doi-access=free }}

Among the studies done using PSPP are one about posttraumatic stress in adolescents,{{cite journal |last1=Marthoenis |first1=Marthoenis |title=Prevalence and determinants of posttraumatic stress in adolescents following an earthquake |journal=Indian J Psychiatry |date=2019 |volume=61 |issue=5 |pages=526–528 |doi=10.4103/psychiatry.IndianJPsychiatry_35_19 |pmid=31579181 |pmc=6767826 |doi-access=free }} another about nutrition software,{{cite journal |last1=Abbassi |first1=A |title=5PSQ-018 Implementation of parenteral nutrition prescribing software in a neonatal intensive care unit |journal=European Journal of Hospital Pharmacy |date=2019 |volume=26 |issue=suppl 1 |page=A209-A210 |url=https://ejhp.bmj.com/content/26/Suppl_1/A209.2 |access-date=16 June 2022}} and another about internet addiction.{{cite journal |last1=Kumari |first1=Rashmi |title=Prevalence and determinants of Internet addiction among the students of professional colleges in the Jammu region |journal=J Family Med Prim Care |date=2022 |volume=11 |issue=1 |pages=325–329 |doi=10.4103/jfmpc.jfmpc_991_21 |pmid=35309600 |pmc=8930114 |doi-access=free }}
