Question

listed below are contributions (in dollars) made to two presidential candidates in a recent election. find the coefficient of variance for each data set. is thee a difference in variation between the two data sets.

1859   881   872   1806   1625   1000   250   1000   1500

1994   388   1701   1578   672   1550

471    460    1402   560   1491   645   1069    228     1018

1255  805     347    98      758    1377  

the cefficient of variation for the contributions to candidate A is =

candidate A

1859   881   872   1806   1625   1000   250   1000   1500

1994   388   1701   1578   672   1550

candidate B

471    460    1402   560   1491   645   1069    228     1018

1255  805     347    98      758    1377  

Explanation / Answer

from above data

hence coefficient of variation for A =std deviation/mean =555.39/1245.07=0.446

and coefficient of variation for B =std deviation/mean =449.77/798.93=0.563

from above it is visible that variation in B is more with respect to A.
