Define the following terms:

(1)Mean

(2)Median

(3)Mode

(4)Range

(5)Variance

(6)Standard Deviation

(7)Coefficient ofVariation

(b)Show the formulas for the above terms (using the symbols --- you do not have to type the symbols).

(c)Put thenumbers from your print-out into the formulasto show how excel computed the Summary Measures.(You do not need to calculate every(x -)²value for the variance.Hint: You can work backward through the variance formula to determine (x -)² --- excel computed the value for the variance and you know the value for "n", so you can solve for the missing value in the formula for the variance which equals (x -)²).
