How to find a coefficient of variation in Excel. You can calculate the coefficient of variation in Excel using the formulas for standard deviation and mean. For a given column of data (i.e. A1:A10), you could enter: “=stdev(A1:A10)/average(A1:A10)) then multiply by 100. ...
A negative correlation coefficient tells us that if one variable increases, other variable decreases. A correlation of -1.0 is a perfect negative correlation. This means that if x increases by 1 unit, y decreases by 1 unit. A positive correlation coefficient tells us that if one variable's va...

Calculating the correlation coefficient with the CORREL function Let’s see how to calculate the correlation coefficient in Microsoft Excel. In our data set the dependent variable (variable y) is the final score, and the independent variable (Variable x) is the number of study hours. Because the...
To calculate the coefficient of variation, first find the mean, then the sum of squares, and then work out the standard deviation. With that information at hand, it is possible to calculate the coefficient of variation by dividing the standard deviation by the mean.2 The Bottom Line The coef...
Enter this information in an empty cell to find R-squared using a single formula: =RSQ([Data set 1],[Data set 2]).3 The Bottom Line R-squared is a statistical measure that explains the variance of one variable using the variance of another. The initial result of the calculation isn’...
