What is dispersion in statistics?
Statistical dispersion, a quantifiable variation of measurements of differing members of a population
What is despersion?
Dispersion is an abstract quality of a sample of data. Dispersion is how far apart or scattered the data values appear to be. Common measures of dispersion are the data range and standard deviation.
Which measure of dispersion represents variation from the mean?
Are you talking of this in means of Statistics? If you are, then the variation from the mean is measured in standard deviation.
What is the relative dispersion with the mean of 45000 and a standard deviation of 9000?
Relative dispersion = coefficient of variation = (9000/45000)(100) = 20.
What is the importance of coefficient of variation?
It's a way of obtaining a measure of dispersion that is dimension-free.
What is dispersion and various measures of dispersion?
Dispersion is the act of spreading people or things (like seeds) out over a large area. Measures of dispersion tell us the degree of variation of values in a sample or population.

What is measure of variation?
A measure of variation, also called a measure of dispersion, is a type of measurement that details how a set of data is scattered from a central or neutral point of origin. Range, variance and standard deviation are three measures of variation that are commonly used.

The measure of dispersion most affected by one extreme value is the?
coefficient of variation

It's a way of obtaining a measure of dispersion that is dimension-free.
What does dispersion indicate about the data?
correlation which can be strong or weak
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)
How can you describe variation in a set of data?
measures of variation
What does symbolic data means-?
Symbolic data differ from standard data in that they contain internal variation.
