sizedistribution
Size distribution describes how a population’s sizes are allocated across a range. It expresses the relative frequency of sizes and can be represented as a number-based, volume-based, or cumulative distribution.
In particle size analysis, distributions are summarized by percentile values such as D10, D50, and D90, and
Measurement methods include sieve analysis for coarse particles; laser diffraction or dynamic light scattering for intermediate
Applications span geology and soil science (grain-size distribution in sediments and soils), materials science and manufacturing
Interpretation notes: distributions can be unimodal or multimodal; sample representativeness and measurement biases can affect results.
