Step 1
The coefficient of variance is a statistical measure of the dispersion of data points in a data series around the mean. It is expressed as a percentage and is calculated by dividing the standard deviation (σ) by the mean (μ) and then multiplying by 100. The Show more…

Given the following set of data, what is the variance? [2, 6, 8, 3, 7, 9, 1, 4]
Madhur L.
For two data sets, each with size 5 , the variances are given to be 4 and 5 and the corresponding means are given to be 2 and 4 , respectively. The variance of the combined data set is (A) $\frac{11}{2}$ (B) 6 (C) $\frac{13}{2}$ (D) $\frac{5}{2}$
a. Calculate the covariance of the set of data $(20,10),(30,50),(60,30),(80,20),(110,60),$ and (120,10). b. Calculate the standard deviation of the six $x$ values and the standard deviation of the six $y$ values. c. Calculate $r,$ the coefficient of linear correlation, for the data in part a. d. Compare these results to those found in the text for Example 13.1 (pp. $613-616$ ).
