Transformation of Frequency Distributions [PDF]

open access: yesNature, 1948
FREQUENCY distributions of numbers of eggs, insects, spores, or other biological entities are descriptive of discrete variation, and can never be represented exactly by a normal distribution or by any other distribution of a continuous variate. Nevertheless, when the number of observations and the range of variation is large, such distributions may ...
