Education: Attended tennis training centers in Switzerland.

Second, we can infer that Federer does not engage in any short-term strategic tanking while playing. Even when he loses, the matches are rarely lopsided and almost every individual game is competitive.

A nuanced analysis of the chair umpire’s point-by-point score sheet in Simpson’s Paradox matches would reveal that Federer often wins his service games by a 40-0 or 40-15 count, frequently loses his return games after one or more deuces, and drops tightly-contested tiebreakers when the set score reaches 6-6.

At one end of the spectrum was American player John Isner.

At 6’10,” Isner unleashes one of the most intimidating serves in tennis history.

Simpson’s Paradox is a statistical quirk where seemingly correlated variables are reversed when combined.

The application to tennis is nuanced: In tennis, a derivative of Simpson’s Paradox is seen in the small percentage of matches where players win more individual points than their opponent, but lose the overall match.This anomaly is an artifact of tennis’s decidedly unique scoring system.Its “best of N” format (best of three sets, usually, or best of five sets in some men’s professional matches) follows a point-game-set-match hierarchy with neither a running score nor a clock. The only point the winning player win is the last one.This result surprised us, as it differed wildly from other players who had similarly won multiple Grand Slam singles titles.Andre Agassi, Rafael Nadal, Pete Sampras, Sergi Bruguera, Marat Safin, Lleyton Hewitt, Yevgeny Kafelnikov, and Gustavo Kuerten were all .500 or better in Simpson’s Paradox matches. There are two non-mutually exclusive explanations for Federer’s curious results.In completed matches, he was 4-24 in contests where the winner prevailed on less than 50 percent of the total points.Federer’s winning percentage in these matches (14.29 percent) was the worst among all 72 players in the sample who participated in at least 20 matches of this type during their careers.However, Federer also holds the dubious distinction of having the worst record among players active since 1990 in so-called “Simpson’s Paradox” matches–those where the loser of the match wins more points than the winner.On the surface, his 4-24 record in such matches may seem hard to reconcile with the rest of his stellar statistics.A deeper inquiry, however, reveals mathematical proof of Federer’s unequaled in-match competitiveness over the course of his career.But first, some background on this arithmetic oddity.
