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

Coeff of Variation = Mean/SD


How do you calculate coefficient of variation?

The coefficient of variation is usually calculated by diving the standard deviation by the mean of a particular set of data. The coefficient of variation is usually expressed as CV.


Is the the coefficient of variation for a data set is the mean divided by the standard deviation expressed as a percentage?

no


What is the coefficient of variation?

The coefficient of variation is the ratio between the standard deviation and the mean.


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 difference between standard deviation and mean?

The mean is the average value and the standard deviation is the variation from the mean value.


What are the advantages and disadvantages of coefficient of variation?

One the main advantage of using the coefficient of variation over the standard deviation to measure volatility is the fact that CV is normalized and can be used to directly compare different asset's volatility. The standard deviation must be used in the context of the mean of the data.


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.


How do you calculate coefficient of variation in spss?

The coefficient of variation is a method of measuring how spread out the values ​​in a data set are relative to the mean. It is calculated as follows: Coefficient of variation = Οƒ / ΞΌ Where: Οƒ = standard deviation of the data set ΞΌ = average of the data set If you want to know more about it, you can visit SilverLake Consulting which will help you calculate the coefficient of variation in spss.


What does it mean if the mean is doubled but the standard deviation is the same?

The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved.


Why do we need the standard deviation?

The standard deviation is a measure of the spread of data.
