• In a described farm located in the UK the average salary of the employees is £ 3500 along with a standard deviation of £150
• The similar firm has a local branch in middle Asia whether the average salaries are Kshs 8500 along with a standard deviation of Kshs.800

Find out the coefficient of variation in the two firms and briefly comment on the degree of dispersion of the salaries in the two firms.

First firm in the UK

  C.O.V             = (150/3500 )    x 100

            = 4.29%

Second firm in middle Asia

C.O.V  = (800/8500)   x 100

= 9.4%

Conclusively, as 4.29 percent < 9.4 percent then the salaries offered by the firm in UK is much closer to the mean described them in the case to the local branch in middle Asia
