Particle Size Result Interpretation Number vs. Volume
Interpreting results of a particle size measurement requires an understanding of which technique was used and the basis of the calculations. Each technique generates a different result since each measures different physical properties of the sample. Once the physical property is measured a calculation of some type generates a representation of a particle size distribution.

Multimodal distributionWikipedia
Statistical tests. A number of tests are available to determine if a data set is distributed in a bimodal (or multimodal) fashion. Graphical methods. In the study of sediments particle size is frequently bimodal. Empirically it has been found useful to plot the frequency against the log( size ) of the particles.

Abstract. A series of in situ measurements made by optical particle counters (OPCs) at Laramie Wyoming provides size-resolved stratospheric aerosol concentration data over the period 1971–2018. A subset of these data covering the period of 2008–2017 is analyzed in this study for the purpose of assessing the sensitivity of the stratospheric aerosol phase function to the aerosol size
