Before a championship soccer match, Emek and Luna compared their team with its opponent using season statistics. Their team had increased its goals scored from 24 early in the season to 33 recently, an increase of 9 goals. The opponent had reduced its goals allowed from 20 to 12, a decrease of 8 goals. At first, Emek thought their team's 9-goal change was greater. Luna suggested comparing percentages because the starting values were different. Their team's increase was 9 out of 24, or 37.5 percent. The opponent's decrease was 8 out of 20, or 40 percent. Although its raw change was smaller, the opponent had made the greater percentage improvement. Knowing they faced a much stronger defense, Emek and Luna planned a patient attacking strategy with careful passes. Their percentage comparison gave the team a clearer picture of the challenge ahead.
