A post on the website of the getstats campaign offers a dozen tips for journalists, who “increasingly have to have at least minimal competence in understanding stats and data, if they are going to do a creditable job”.
From a warning to think about the motivation of whoever “cooked up” the number in a press release, to putting figures in context to add to their impact, the list is aimed at the basic skill set that getstats thinks are “the basis for a journalistic career in the 21st century”. Your views on the items in the list are invited via the webpage.
