For those of you who like to follow bad presentations of statistical 
data in the news, here's a real doosie.
http://news.yahoo.com/s/ap/20090107/ap_on_he_me/med_teen_births

Note that in the graph that it says these numbers are "per 1,000 births" 
but then next to the top bar, it says "68.4%" (rather than 68.4 per 
1000). So, actually only 6.84% of births in Mississippi are to teen 
mothers.

I checked the source -- a CDCP report -- and it does not make the % 
mistake. The graph seems to have been compiled by AP.

What may be worse, the base used (per 1000 live births) will confuse 
many, who will assume that 68.4% of (presumably female) *teens* are 
geting pregnant in MS.

Best regards,
Chris
