If q1q2q3 are three quartiles then Coefficent of quartile deviation is?
coefficient of quartile deviation is = (q3-q1)/(q3+q1)
How do you calculate a coefficient knowing the expected rate of return and standard deviation?
It depends on what the underlying distribution is and which coefficient you want to calculate.
What do you mean when you say that the coefficient of variation has no units?
Suppose the mean of a sample is 1.72 metres, and the standard deviation of the sample is 3.44 metres. (Notice that the sample mean and the standard deviation will always have the same units.) Then the coefficient of variation will be 1.72 metres / 3.44 metres = 0.5. The units in the mean and standard deviation 'cancel out'-always.
What is the coefficient of variation?
The coefficient of variation is the ratio between the standard deviation and the mean.
Why use standard deviation and not average deviation?
Because the average deviation will always be zero.
What is coefficient of quartile deviation?
What is coefficient of quartile deviation?
What is the formula for coefficient of quartile deviation?
coefficient of quartile deviation: (Q3-Q1)/(Q3+Q1)
Coefficient of Deviation?
Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.
Notes about Bowel's coefficient of skewness and Kelly's coefficient of skewness?
describe the properties of the standard deviation.
If q1q2q3 are three quartiles then Coefficent of quartile deviation is?
coefficient of quartile deviation is = (q3-q1)/(q3+q1)
How do you calculate a coefficient knowing the expected rate of return and standard deviation?
It depends on what the underlying distribution is and which coefficient you want to calculate.
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 standard deviation and coefficient of variation?
standard deviation only measures the average deviation of the given variable from the mean whereas the coefficient of variation is = sd\mean Written as "cv" If cv>1 More variation If cv<1 and closer to 0 Less variation
Is the the coefficient of variation for a data set is the mean divided by the standard deviation expressed as a percentage?
no
Determine Coefficient of variation from the mean and standard deviation?
Coeff of Variation = Mean/SD
