Arithmetic mean, or Average, is the sum of N numbers divided by N. Geometric mean is the Nth root of Youth And Climate Change In Africa, 1J-K). Because fluorescent intensity increases logarithmically, arithmetic mean quickly becomes useless to generalize a population of events, as a right-hand skew causes even more exaggeration of the mean. The results can then be used to measure the intensity of staining, as well as its degree of homogeneity.
