In contrast, campus licenses for SPSS can cost upwards of €30,000 per year.

Most notably, Bayesian hypothesis tests can quantify evidence in favor of the null hypothesis, and they allow users to monitor evidence continually, as the data accumulate.Īnother advantage of JASP for students and universities is that it comes free of charge. Compared with classical hypothesis tests that produce p values, Bayesian hypothesis tests have a number of distinct practical advantages.

This simplicity reflects the design philosophy that good software gets out of the users’ way, letting them focus on what they want to achieve without first having to “learn the software.” Far from dumbing down statistics through “point-and-click,” we believe that JASP allows students and researchers to pay attention to what matters: not the software, but the analyses and the results.Īs mentioned, JASP implements a number of Bayesian analyses, making heavy use of Morey and Rouder’s (2015) BayesFactor R package, which implements a range of Bayesian hypothesis tests.
In JASP, analyses are clearly labeled for instance, the ANOVA is available through a menu item called “ANOVA.” And results are user-friendly: a minimalist, attractive ANOVA table, already in APA format and waiting to be copied and pasted into Word (see Figure 1 for an example). JASP maintains a minimalist design philosophy.

Additional analyses are continually added to JASP, such that it will quickly become a comprehensive alternative to SPSS.įigure 1. This set of analysis tools provides a solid base for most students and researchers. At time of writing, JASP version 0.6 implements the following analysis tools in both their classical and Bayesian manifestations: JASP distinguishes itself from SPSS by being as simple, intuitive, and approachable as possible, and by making accessible some of the latest developments in Bayesian analyses. With a European Research Council grant, our project “Bayes or Bust: Sensible Hypothesis Tests for Social Scientists” has allowed us to develop JASP, a free and open statistical software package designed to be familiar to users of SPSS.
These emerging issues are unfortunate for the SPSS user base, but at the same time they create an opportunity for the scientific community to produce a compelling alternative. The SPSS menu system remains deep and complex, analysis options are not always intuitively labeled, and SPSS often produces substantial output, requiring users to engage in a quest to find the values of interest. Similarly, SPSS has not kept pace with trends toward ease and simplicity in user-interface design. Although statisticians have proposed many useful analyses in the last few years, many of these proposals remain unavailable in SPSS.
More recently, however, SPSS has not been as actively developed as it once was. Over the years, this ability to adapt and change has allowed SPSS to remain relevant and helpful for both teaching and research.

Finally, with the ascent of Microsoft Windows and other graphical operating systems, SPSS became equipped with a graphical user interface. As computing advanced, SPSS continued to keep pace next, it became available for mainframe environments, and then, with the rise of the “personal computer,” SPSS became available for command-based DOS environments. Its pedigree reaches back as far as the 1960s, when SPSS was first programmed with punch cards. The last few decades have witnessed the growth of SPSS as the statistical software of choice across a wide range of academic disciplines. Current members of the JASP team, Amsterdam division, are, from left to right, Quentin Gronau, Dora Matzke, Ravi Selker, Eric-Jan Wagenmakers, Alexander Ly, Maarten Marsman, Tahira Jamil, and Jonathon Love.
