Both schools should work on the same problem, but may draw different conclusions about which ranking is best. The world tennis association has decided it wants to produce a 'world ranking' for the leading players in the world today - and they have called you in to help.
Tennis has a number of tournaments.
As a starting point, the world association wants you to create the rankings for men, by giving players points depending on how well they do in tournaments. Devise your own points allocation for different strengths of tournament. Another way of ranking is to take a player's best four performances, and add up the totals for these. So depending on your points system, Henman's best four scores might be Wimbledon, Beckenham, Rome and Tokyo. In this example, we have only looked at the results for one year.
