Performing a particle size analysis is the best way to answer the question:
What size are those particles? Once the analysis is complete the user has
a variety of approaches for reporting the result. Some
people prefer a single
number answer—what is the average size? More experienced particle scientists
cringe when they hear this question, knowing that a single number cannot describe
the distribution of the sample. A better approach is to report
both a central point of
the distribution along with one or more values to describe the width of distribution.
Other approaches are also described in this document.
