    3. Statistical analysis and expression of results

    Once an equivalent size and a suitable measurement technique have been selected, particle size analysis can be performed. Generally speaking, the particle size analysis of a powder consists of determining the size of a significant and representative set (sample) of particles and circumscribing this information using ad hoc statistical formalisms. This analysis requires reworking the raw results to establish the granulometric distribution or breakdown of the population in the form of a table, graph or mathematical expression (distribution law or function).

    3.1 Particle size distribution function

    Like any rigorous statistical analysis of a population of individuals, particle size analysis is based on the distribution (or density) function of the independent variable...
