Replication data for: Midpoint Misperceptions on 1-to-10 Scales

Scales that range from 1 to 10 are a common tool in political science and other disciplines, but this study reports evidence that from the 2005-2008 wave of the World Values Survey suggesting that many respondents interpret 5 as the midpoint of a 1-to-10 scale. This misperception would bias item means downward, introduce inferential uncertainty, and defeat the purpose of a forced-choice scale.
