Mean> Median?

by sampath » Fri Aug 12, 2011 12:13 pm
Five cards are to be selected at random from 10 cards
numbered 1 to 10. How many ways are possible that the
average of five numbers selected will be greater than the
median?

I agree with force5. Having said that, it is helpful to know this general idea:

The mean is greater than the median when there are more outliers to the right.
The mean is less than the median when there are more outliers to the left.

For example, which do you think is greater, mean national income or median national income?
Mean is greater, it is pulled up by huge earners, whose earnings barely impact the median at all.
