Gaussian distribution

A random distribution of events that is graphed as the famous "bell-shaped curve." It is used to represent a normal or statistically probable outcome and shows most samples falling closer to the mean value. See Gaussian noise and Gaussian blur.

10,11) The diagnostic relevance is obvious: If a sufficiently high number of physiological parameters such as resistance or conductivity values of the body are measured, the probability of measuring definite values in small preset ranges between the lowest and the highest resistance (or conductivity) values will follow the random Gaussian distribution, only if the regulation has been completely broken down.
