These calculations are performed both arithmetically and geometrically, using both metric and phi units. The software employs both the method of moments and the graphical methods of Folk and Ward (1957) to provide a comprehensive statistical analysis.
Because the original v 9.1 is no longer supported, the geoscience community has created "forks" and improvements:
While highly versatile, users should be aware that older versions of GRADISTAT might have compatibility issues with the newest versions of Excel (due to macro security updates). Always ensure your input data units match the expected input format (e.g., phi vs. millimeters). Conclusion
