It’s a spreadsheet-based tool (developed by Simon Blott) that calculates standard grain size statistics using the method of moments and the Folk and Ward method. It saves hours of work by automatically generating cumulative curves and statistical outputs.

Before this software, calculating complex statistics for large datasets was a laborious manual process. GRADISTAT simplifies this by providing robust, standardized descriptive terms (e.g., "very well sorted" or "fine skewed") based on recognized sedimentological scales. This standardization is crucial for mitigating coastal erosion, managing floods, and conducting environmental impact studies. GRADISTAT software - Kenneth Pye Associates Ltd gradistat v 91 free
