Question

During fiscal year 1986, McDonnell corporation was second only to Lockheed Missiles & Spice Company in net value of U.S Department of defense prime contract awards over $25,000 for research, development, test and evaluation. The work awarded to McDonnell was done in 20 locations, with a break down(millions of dollars) as follows:

                                 $0.1    $4.1      $0.3       $11.2     $0.2       $103.8   $0.3       $434.6   $0.1       $0.7

                                 $-1.1 $2.6       $4.9       $0.1       $6.2       $354.7   $0.2       $1.3       $0.7       $0.2                                

Determine the mean, mode and median for these data

In this case, does the mode appear to be a good measure of the typical amount of work that was awarded to a McDonnell division during that year? Why

Explanation / Answer

-1.1, 0.1, 0.1, 0.1, 0.2, 0.2, 0.2, 0.3, 0.3, 0.7, 0.7, 1.3, 2.6, 4.1, 4.9, 6.2, 11.2, 103.8, 354.7, 434.6

mean = (-1.1+ 0.1 + 0.1 + 0.1 + 0.2 + 0.2 + 0.2 + 0.3 + 0.3 + 0.7 + 0.7 + 1.3 + 2.6 + 4.1 + 4.9 + 6.2 + 11.2 + 103.8 + 354.7 + 434.6)/20

        = 46.26

mode = 0.1, 0.2

median = (0.7 + 0.7)/2 = 0.7

No because there are larger value than mode.
