Score voting: Difference between revisions

'''Range voting''', or '''ratings summation''', or '''average voting''', or '''cardinal ratings''' is a [[voting system]] used for single or multiple-seat elections. It is also used on the web - for rating movies (Internet Movie Database), comments (Kuro5hin), and many other things.

CardinalRange Ratingsvoting uses a [[ratings ballot]]; that is, each voter rates each candidate with a number. In "pure Cardinalrange Ratingsvoting", each voter may give any candidate any real number, but as the potential for [[tactical voting]] is huge, most systems use upper and lower bounds. For example, each voter might give a real number between -1 and 1, or an integer between 1 and 10.

CardinalRange Ratingsvoting in which only two different votes may be submitted (0 and 1, for example) is equivalent to [[approval voting]].

CardinalRange Ratingsvoting satisfies the [[monotonicity criterion]].

In general, the optimal strategy for Cardinalrange Ratingsvoting is to vote it identically to approval voting, so that all candidates are given either the maximum score or the minimum score. For more detailed strategies, see [[approval voting]].
