(4) Group decision making. The student uses mathematical processes to apply decision-making schemes. The student analyzes the effects of multiple types of weighted voting and applies multiple voting concepts to real-world situations. The student is expected to:

• (A) describe the concept of a preference schedule and how to use it;

• (B) explain how particular decision-making schemes work;

• (C) determine the outcome for various voting methods, given the voters' preferences;

• (D) explain how different voting schemes or the order of voting can lead to different results;

• (E) describe the impact of various strategies on the results of the decision-making process;

• (F) explain the impact of Arrow's Impossibility Theorem;

• (G) relate the meaning of approval voting;

• (H) explain the need for weighted voting and how it works;

• (I) identify voting concepts such as Borda count, Condorcet winner, dummy voter, and coalition; and

• (J) compute the Banzhaf power index and explain its significance.
