One publication is Chance, which is copublished quarterly by the American Statistical Association and Taylor and Francis Group. The magazine is designed for anyone who has an interest in the analysis of data, informally highlighting sound statistical practice. CHANCE is not a technical magazine, but rather a cultural record of an evolving field, intended to entertain as well as inform.
Since its creation in 1988, CHANCE has covered such topics as the 1990 census adjustment and the redesigned population survey, sports, the environment, DNA evidence in the courts, a variety of medical issues—even how to win on "Jeopardy." CHANCE offers a unique opportunity to reach beyond statistics professionals to a more general audience."
