The scheme shows a Gaussian-type distribution of a species of tick on a population of hosts, with every host carrying ticks and a variable number of ticks on each host, and a negative binomial distribution, showing how most ticks are concentrated on a few hosts, while most hosts do not carry ticks at all. Both distributions are displayed as a chart. Mean number of ticks and standard deviation are the same for both distributions. Created with BioRender.com.
