How find margin of error
Web8 sep. 2016 · To determine whether or not the race is too close to call, we need to calculate a new margin of error for the difference between the two candidates’ levels of support. The size of this margin is generally about twice that of the margin for an individual candidate. WebSee that \(4/5\) of the values fall within the margin of error: \(1.2\) deviates from \(2\) by more than \(0.5\).
