International Statistical Literacy Project
The ISLT website has curated many Statistical literacy websites. In part it attempts to point to sound educational material for Journalists and media around how to correctly report statistics, thereby generally increase the statistical literacy of the public.
The following two resources were prepared for the United Nations:
Making data meaningful Part 1 (Telling a story)
Making data meaningful Part 2 (Graphical presentations)
There are many other resources on the website.
