StatsDirect is desktop statistical analysis software for research, education, and learning statistics.

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.
