Draw your own conclusion based on the following factual data:
Using these premises:
Medians are used to be resistant to skewed data (unproportionate data), means are not resistant, they show that there is some disproportionality according to how much they differ from the median.
In 1975 the median household income was:
$11,800
The mean was $13,779.
In 2006 the median was $48,201
and the mean was $66,570
Simple computation gives us
1975: 13779/11800 = the mean is 16% larger than the median.
2006: 66570/48201 = the mean is 38% larger than the median.
