The coefficient of variation is a statistical measure that helps you understand how much variation is in the data compared to the average. Let’s say you have sales data for different months and want to see how consistent your sales are. The CV gives you a percentage that shows how much y...
By comparing each portfolio's standard deviation of returns to the mean return, you can determine their risk-return profiles. This measure can show which portfolios offer higher returns relative to the level of risk involved. To calculate each portfolio’s coefficient of variation, let’s start b...
How to Find the Coefficient of Variation What is a good CV? Disadvantages What is the Coefficient of Variation? The coefficient of variation (CV) is a measure of relativevariability. For example, the expression “The standard deviation is 15% of the mean” is a CV. It is theratioof the...
The coefficient of variation (CV), also known as "relative variability," is equal to the standard deviation of a distribution divided by its mean. As discussed in John Freund's "Mathematical Statistics," the CV differs from the variance in that the mean "normalizes" the CV in a way, mak...
Now that you have these two values, take note of their cells and select another empty cell to calculate the coefficient of variation. Input the following function:=D2/D3. Don’t forget to replace our example numbers with your own.
Covariance is a measure of how two variables change together. It is used to determine whether two variables are linearly related. If the covariance is positive, the variables tend to increase or decrease together. If the covariance is negative, the variables tend to move in opposite directions....

Therefore, we were not able to determine if there is a gene dependency for the best method. To resolve this matter, a wider range of expression levels per gene should be examined. We also tested if the correlations between the microarray and Real Time RT-PCR data depended on signal ...
In finance, the coefficient of variation allowsinvestorsto determine how much volatility, or risk, is assumed in comparison to the amount of return expected from investments. The lower the ratio of the standard deviation to mean return, the better the risk-return tradeoff. ...
