Flocks used for the early detection of mosquito-borne pathogens that infect the birds without causing symptoms.

A distribution where the data points cluster more toward one side of the scale than the other, creating a curve that is not symmetrical.

In statistics, how different the data points in a distribution are, that is, how closely clustered they are to the mean.

A measure of the dispersion of a set of data points, as measured by their distance from the mean, and defined as the square root of the mean of the squares (r.m.s) of those distances. The square root of the variance.
