It is often used in biology, geology, and other fields to study the size and distribution of organisms or particles within a population.
[1] The size of an organism or particle is typically measured using a physical characteristic such as length, width, or mass.
The size–frequency distribution is then plotted on a graph, with the size of the organisms or particles on the x-axis and the frequency of occurrence on the y-axis.
They are used in a wide range of fields, including biology, geology, and engineering, to study the size and distribution of organisms, particles, and other objects.
The size–frequency distribution of the fish in the lake with a high food availability may show faster growth and larger sizes, while the size–frequency distribution of the fish in the lake with a low food availability may show slower growth and smaller sizes.
Size–frequency distribution is often used in conjunction with other statistical analysis techniques to gain a more comprehensive understanding of population dynamics.
