9.1 — Gradistat V

The last official version (9.1) was released in the early 2010s (some sources say 2008). The author has not issued updates, patches, or 64-bit versions. There is no official support, though user forums and academic blogs provide workarounds.

Unlike complex GIS or coding-based solutions (e.g., R's G2Sd package or Python scripts), Gradistat v 9.1 operates entirely within Microsoft Excel. This makes it accessible, user-friendly, and immediately deployable for students, lab technicians, and professionals who are already comfortable with spreadsheet software. gradistat v 9.1
