§    ABSTRACT: The contagious distributions are common in biology and agronomy, by example. With spatial distribution of weeds, insects by area, plant etc. The main characteristic of such data is the variance larger than the mean, as a consequence of the clumps. Sampling and statistical analysis of such data were discussed.

§    KEYWORDS: Contagious distribution; relation variance/mean; overdispersion.
