The meaning of COEFFICIENT OF VARIATION is the ratio of the measure of variability, usually the standard deviation, to an average, usually the arithmetical mean, about which the variation occurs.
The coefficient of variation formula can be performed in Excel by first using the standard deviation function for a data set. Next, calculate the mean by using the Excel function provided. Since the coefficient of variation is the standard deviation divided by the mean, divide the cell containing...

Meaning of the Coefficient of Variation Coefficient of Variation (CV) is a statistical measure that helps to measure the relative variability of a given data series. Or, we can say it measures the distribution of data points in accordance with the mean. Since the key factors involved in the ...
Meaning and definition of Coefficient of Variation The coefficient of variation (CV) refers to a statistical measure of the distribution of data points in a data series around the mean. It represents the ratio of the...
Investment 2 has a 10-year average return of 12% and a standard deviation of 6%, which yields a CV of 0.5. Even though Investment 1 had a higher overall return, Investment 2 historically had a lower coefficient of variation, meaning it offered a more favorable risk/reward trade-off for ...
Note:The Coefficient of Variation should only be used to compare positive data on aratio scale. The CV has little or no meaning for measurements on aninterval scale. Examples of interval scales include temperatures in Celsius or Fahrenheit, while the Kelvin scale is a ratio scale that starts ...
The coefficient of determination also explains that how well the regression line fits the statistical data. The closer the regression line to the points plotted on a scatter diagram, the more likely it explains all the variation and the farther the line from the points the lesser is the ability...
The coefficient of determination, R2, is used to analyze how differences in onevariablecan be explained by a difference in a second variable. For example,whena person gets pregnant has a direct relation to when they give birth. More specifically, R-squared gives you the percentage variation in...
The meaning of COEFFICIENT OF VELOCITY is the ratio of the actual velocity to the theoretical velocity of a fluid jet.
