Most professional golfers and analysts think that winning on the PGA Tour peaks when golfers are in their thirties. Rather than relying on educated guesses, we can actually use available statistical data to determine the actual ages at which golfers peak their golf game. We can also test the hypothesis that age affects winning professional golf tournaments. Using data from the web sites of the Golf Channel, the PGA Tour, the European PGA Tour, and the LPGA Tour, I calculated the mean, the median, and the mode ages at which professional golfers on the PGA, European PGA, Champions, and LPGA Tours had won between 2003 and 2007. More specifically, the ages at which golfers on the PGA, European PGA, Champions, and LPGA Tours peak their wins seem to be 35, 30, 52, and 25, respectively. The regression analysis I have conducted seems to support my hypothesis that age affects winning professional golf tournaments.
