: Fill in the green cells with sample identity, analyst name, and date. Run Analysis : Click the "Calculate Statistics"

Displays sigmoidal curves mapped against sieve apertures to visually determine percentile values like D10cap D sub 10 D50cap D sub 50 (median), and D90cap D sub 90

The program is designed for speed, capable of processing approximately . Its core functionality includes:

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. gradistat v 91 free

The application accepts particle size distributions from standard or non-standard testing techniques and processes data with exceptional efficiency. The key quantitative and descriptive metrics generated by the software include:

: A revised version with greater functionality currently under development.

For both methods, GRADISTAT outputs four critical statistics: The average particle size. : Fill in the green cells with sample

Provides cumulative distribution curves, frequency histograms, and text descriptions automatically.

Easy to input data and instantly produce reports. Why Use GRADISTAT v9.1?

Gradistat (Version 9.1) is a Microsoft Excel macro-enabled workbook developed by and Kenneth Pye of the now-closed Kenneth Pye Associates Ltd. (later part of Foster Wheeler). It was first introduced in the early 2000s and became the industry standard because it automated the tedious, error-prone process of calculating Folk and Ward (1957) graphical statistics, moments statistics, and the logarithmic method of moments. If you expect graphs

GradiStat v9.1 Free is a no-frills, deterministic tool designed for one thing: (specifically, calculating the statistical optimum and tolerance of species along an environmental gradient). If you are a paleontologist or ecologist needing to replicate a 1990s transfer function, this is gold. If you expect graphs, intuitive data handling, or any support for multivariate analysis, look elsewhere.

GRADISTAT is a widely used designed for the rapid analysis of grain size statistics from sediment samples.
