Gradistat V 91 Free [new]
For those of you working in sedimentology, geology, or environmental science, you’re likely familiar with —the go-to Microsoft Excel-based program for rapid grain size statistics analysis.
Gradistat V 9.1 is a sophisticated statistical software package designed to facilitate data analysis, visualization, and interpretation. It offers a wide range of statistical tests, regression analysis, and data manipulation tools, making it an indispensable resource for anyone working with data. The software is particularly popular among researchers, academics, and students due to its user-friendly interface, flexibility, and accuracy.
Check the README sheet inside Gradistat or search geoscience forums like GeoNet, ResearchGate, or the SEPM discussion board.
Choose your preferred statistical methods from the options panel. You can select whether you want the calculations to output in metric or Phi units, and choose between the Folk and Ward or Method of Moments frameworks. Step 3: Run the Program gradistat v 91 free
) units alongside the exact weight of sediment retained on each sieve. Ensure you account for the pan weight at the bottom. Laser Diffraction Input
: Folk and Ward measures in metric units provide a highly stable basis for comparing compositionally variable sediments.
Click the "Calculate" button to populate the results sheets automatically. System Requirements To run Gradistat v 9.1 smoothly, you simply need: For those of you working in sedimentology, geology,
Double-click the Gradistat file. If a yellow warning bar appears at the top of the screen reading "Security Warning: Macros have been disabled," click Enable Content . Preparing and Inputting Your Data
Assemble your raw data. For sieve analysis, this is typically the weight of sediment (in grams) retained on each sieve screen. For laser diffraction, this is the percentage volume of each particle size class. 2. Inputting Data Open the GRADISTAT Excel file. Input the sieve screen mesh sizes (in mm or phi).
Version 9.1 carries forward the core analytical capabilities, including: You can select whether you want the calculations
The "v91" designation refers to a specific, widely circulated build of the software. While newer versions have been developed to accommodate evolving operating systems and bug fixes, version 9.1 is often cited in older literature and remains a functional workhorse for many researchers. It provides the essential method of moments (geometric and logarithmic) and the Folk and Ward graphical methods. Furthermore, it automatically classifies the sediment based on the Wentworth scale and generates ternary diagrams. For students and researchers working on legacy data or replicating older studies, maintaining access to this specific version is crucial for ensuring methodological consistency.
For over two decades, has been the industry standard for this task. Developed by Simon Blott, this Excel-based program streamlines the calculation of grain size statistics.
Paste your sieve weights or percentage data into the designated input sheet.
