Sorted data
37000,37000,38600,39750,40000,95000
a) mean = (37000+37000+38600+39750+40000+95000)/6
=47891.667 $
b)median = (38600+39750)/2 = 39175 $ (middle most value of sorted data)
c)mode = 37000$ (maximum Freq. That is 2)
d)median is the best choice .
The mean is being skewed by the large salarie/s(here 95000$) . Therefore, in this situation, we would like to have a better measure of central tendency. So taking the median would be a better measure of central tendency in this situation.
