What is the difference between absolute dispersion and relative dispersion in statistics?

Absolute dispersion usually refers to the standard deviation, a measure of variation from the mean, the units of st. dev. are the same as for the data.
Relative dispersion, sometimes called the coefficient of variation, is the result of dividing the st. dev. by the mean, hence it is dimensionless (it may also be presented as a percentage). So a low value of relative dispersion usually implies that the st. dev. is small in comparison to the magnitude of the mean, as in a st. dev. of 6cm for a mean of 4m would give a figure of 0.015 (1.5%) whereas with a mean of 40cm it would be 0.15 or 15%.
However with measurements either side of zero and a mean close to zero the relative dispersion could be greater than 1.
As is usual, interpret with caution.

What is difference between absolute measure of dispersion and relative measures of dispersion?
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.
What is the difference of absolute value and relative value?
Absolute value uses a companies cash flow to determine it's worth. Relative value compares a companies worth to other competitors.
What are absolute relative and polar coordinates?

What information is provided by absolute that cannot be provided by relative dating?

What is difference between relative and absolute age?
In terms of geology, Relative Age is the age of an object in relation to the ages of other objects. Layers of rock, called strata, show the order of events that took place in the past and Absolute Age is the numerical age of an object or event.

What is the difference of absolute age and relative age?
In the absolute age, the value will be exact and direct but in the relative age you will compare the rock with other feature.
What is the difference between the relative age and absolute age of rocks?
Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.
Difference in Relative risk and risk ratio?
There is no difference between the two. Relative risk is the same as relative ratio. Commonly abbreviated as RR, relative risk/ratio is measure of absolute risk in one population as a proportion of absolute risk in another. It is a measure of the strength of association.
What is relative measure?
These measures are calculated for the comparison of dispersion in two or more than two sets of observations. These measures are free of the units in which the original data is measured. If the original data is in dollar or kilometers, we do not use these units with relative measure of dispersion. These measures are a sort of ratio and are called coefficients. Each absolute measure of dispersion can be converted into its relative measure. Thus the relative measures of dispersion are:Coefficient of Range or Coefficient of Dispersion.Coefficient of Quartile Deviation or Quartile Coefficient of Dispersion.Coefficient of Mean Deviation or Mean Deviation of Dispersion.Coefficient of Standard Deviation or Standard Coefficient of Dispersion.Coefficient of Variation (a special case of Standard Coefficient of Dispersion)
