Weasel Words and Weasel Stats

You've probably heard of "weasel words." I want to call the following a "weasel statistic" (from State Farm mailer):

"[we] can help with an average of $507 in savings"

(fine print: "1. Average annual per household savings based on a 2018 national survey by State Farm of new policyholders who reported savings by switching heir auto insurance to State Farm")
