This is a more mathematically rigorous method that uses all the data points. It calculates the arithmetic, geometric, or logarithmic mean, variance, skewness, and kurtosis of the entire distribution. While more mathematically robust, it is also more sensitive to outliers. gradistat v 91 free

The program was developed by Simon J. Blott and Kenneth Pye, and its original methodology was published in the journal Earth Surface Processes and Landforms in 2001. GRADISTAT is designed to run within Microsoft Excel, making it accessible and versatile for researchers.
GradiStat is a grain size distribution and statistics package specifically designed for the analysis of unconsolidated sediments. It was developed by Simon J. Blott and Kenneth Pye and was officially published in the journal Earth Surface Processes and Landforms in 2001. Share public link This is a more mathematically
GRADISTAT processes physical raw weight values gathered from dry sieving, or percentage frequencies outputted from advanced laser granulometers, X-ray sedigraphs, and Coulter counters. It completes a massive list of math calculations automatically, reducing the calculation time to an estimated 50 samples per hour.
