In statistics, a frequency distribution is a table that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.

Suffice it that Poisson was a mathematician and that Poisson's frequency distribution is a good approximation to the binomial distribution as the number of trials increases and probability of success in a single trial is small.
For the first time in cryptology, Friedman treated a frequency distribution as an entity, as a curve whose several points were causally related, not as just a collection of individual letters that happen to stand in a certain order for noncausal (historical) reasons, and to this curve he applied statistical concepts.
Hense, so that he could run a computer analysis of the frequency distribution of its elements.
And then, of course, there's the underlying theory-harmonic relations, wave analysis, frequency distribution, and so on.
