One More New Gizmo!

One more new Gizmo is live, with supporting Exploration Guide and Assessment Questions — it's the Polling: City Gizmo.

This Gizmo provides an interesting study of polls.  How reliable is a given poll for an upcoming election? How likely is it that the outcome predicted in the poll will turn out to be incorrect? What factors increase reliability? Interesting and relevant questions!

Polling: City is a perfect followup to the Polling: Neighborhood Gizmo.
