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 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 the difference in the means as a multiple of the mean absolute deviations?
The difference in the means refers to the numerical difference between the average values of two datasets. The mean absolute deviation (MAD) is a measure of the dispersion of data points around the mean, calculated as the average of the absolute differences between each data point and the mean. When expressing the difference in the means as a multiple of the mean absolute deviations, you are essentially normalizing the difference by the variability of the data, providing a context for how significant the difference is relative to the spread of the data. This ratio helps to understand whether the difference is substantial in relation to the overall variation in the datasets.
What is the difference of absolute value and relative value?

What is absolute error formula?
Absolute and Relative Error Absolute and relative error are two types of error with which every experimental scientist should be familiar. The differences are important. Absolute Error: Absolute error is the amount of physical error in a measurement, period. Let's say a meter stick is used to measure a given distance. The error is rather hastily made, but it is good to ±1mm. This is the absolute error of the measurement. That is, absolute error = ±1mm (0.001m). In terms common to Error Propagation absolute error = Δx where x is any variable. Relative Error: Relative error gives an indication of how good a measurement is relative to the size of the thing being measured. Let's say that two students measure two objects with a meter stick. One student measures the height of a room and gets a value of 3.215 meters ±1mm (0.001m). Another student measures the height of a small cylinder and measures 0.075 meters ±1mm (0.001m). Clearly, the overall accuracy of the ceiling height is much better than that of the 7.5 cm cylinder. The comparative accuracy of these measurements can be determined by looking at their relative errors. relative error = absolute error value of thing measured or in terms common to Error Propagation relative error = Δx x where x is any variable. Now, in our example, relative errorceiling height = 0.001m 3.125m •100 = 0.0003% relativeerrorcylinder height = 0.001m 0.075m •100 = 0.01% Clearly, the relative error in the ceiling height is considerably smaller than the relative error in the cylinder height even though the amount of absolute error is the same in each case.
What is the difference absolute strength and relative strength?
Absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.
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)
What is the difference between absolute strength and relative strength?
Absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.

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.
What is the difference between absolute income and relative income?
Relative income measures your income in relation to other members of society, weighing it against the standards of the day. Absolute income, meanwhile, does not take into consideration those other factors, but simply reflects the total amount of earnings you have received in a given period.
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.
