jamovi vs StatsDirect

jamovi is a free, open-source statistical analysis program for working with data through point-and-click controls or scripting. It supports statistical tests, regression models, and Bayesian analysis, and imports SPSS (.sav), SAS, Stata, CSV, and Excel files. The spreadsheet-style interface lets users choose variables and settings, with results updating as they work; analysis does not require writing code. The desktop application runs on Windows, macOS, and Linux, and works offline after installation. Cloud access runs in a browser without installation or setup, including on modern browsers, Chromebooks, lab computers, tablets, and other devices. The free Cloud Guest plan requires no credit card, but guest sessions lack queue skipping, unlimited session length, longer idle timeouts, and larger datasets. jamovi is powered by R and displays the R syntax behind analyses. Data, analyses, and results can be saved together in a shareable, reproducible file. Cloud can connect to OneDrive to open and save jamovi files; Cloud plans include the full module library.

StatsDirect is desktop statistical analysis software for research, education, and learning statistics. Its methods include regression, ANOVA, meta-analysis, survival analysis, exact tests, sample-size estimation, and Bayesian analysis, with scripting support. The data interface follows an Excel-like layout, while reports use a simple word-processor style. A statistics guide and context-sensitive help explain results and reports. StatsDirect imports Microsoft Excel files (.xlsx and.xls), common spreadsheet data, and formatted or plain text; it can write Excel files and reports in RTF or HTML. The maker describes links with Microsoft Excel and incorporation of R for advanced use. The software emphasizes confidence-interval inference and uses exact profile-likelihood methods wherever practical. It runs on Microsoft Windows, requiring.Net Framework version 10 or later and at least 1GB of free memory. Mac use is through virtual Windows with Parallels or VMware Fusion. The free plan costs nothing, with no license fees or restrictions on uses.
