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.
How you find suspected outlier when you have mean?
Having only the mean is not sufficient to identify outliers. You need some measure of dispersion.
What information about a sample does a mean not provide?
what information about the sample of a mean not provide
What is the difference between Dispersion and Skewness?
distinguish between dispersion and skewness
What does open casting calls mean?
casting call
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 do you mean by measures of central tendency and dispersion?
Common measures of central tendency are the mean, median, mode. Common measures of dispersion are range, interquartile range, variance, standard deviation.

What are the types of dispersion compensation?
The types of dispersion compensation are chromatic dispersion compensation, polarization mode dispersion compensation, and non-linear dispersion compensation. Chromatic dispersion compensation corrects for dispersion caused by different wavelengths of light traveling at different speeds. Polarization mode dispersion compensation addresses differences in travel time for different polarization states of light. Non-linear dispersion compensation manages dispersion that varies with the intensity of the light signal.
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.
Why do you seldom use the mean or average deviation as a measure of dispersion?
because of grace severo
