distinguish between dispersion and skewness

The Absolute Measure of dispersion is basically the measure of variation from the mean such as standard deviation. On the other hand the relative measure of dispersion is basically the position of a certain variable with reference to or as compared with the other variables. Such as the percentiles or the z-score.
Negative skewness means the average (mean) will be less than the median. Positive skewness means the opposite. I'm not sure if any rule holds for the mode.

Answer this question...similarities and differences between normal curve and skewness
Diffusion is generally the process in which a constituent moves through a concentration gradient and dispersion is referred to the bulk flow of the molecules.
Population density shows how many people live in a given area. Dispersion shows where they live in that same are, whether clumped, uniform or randomly.

Normal dispersion occurs where shorter wavelengths travel slower than longer wavelengths. Anomalous dispersion occurs when shorter wavelengths travel faster than longer wavelengths.The zero dispersion point for optic fibres is around 1550 nm, which is why most communications systems use this wavelength.
