Frequency distributions - Open Access .click

Nature, 1950
IN the determination of the size-frequency distribution of a particulate material by sieve analysis, it is often assumed1 that the rate of sieving is proportional to the quantity of material on the sieve. If y is the amount of material of size smaller than the sieve mesh at any time t, this assumption leads to the equation y/y0 = exp (− at), where a is

Species Frequency Distributions

Biometrika, 1969
This paper deals with the branch of statistical ecology which studies the pattern of variation in the abundances of the different species present in a habitat, as distinct from the actual abundances of a fixed set of species. Much of the work in this field has been done by ecologists, the leading contributor being C. B.

Graphing the frequency distribution

Journal of Audiovisual Media in Medicine, 1980
The well designed frequency distribution graph reveals central tendency and dispersion of the data. Close attention to several small points - zero baseline, equal intervals, and number and size of intervals - can distinguish a meaningful graph from a misleading or confusing one. A frequency distribution graph is the visual expression of how often (fre-'
