Abstract: A golf scoring average determining method and system provides a means for golfers to evaluate their current scoring ability with respect to a particular golf course as well as evaluating their average performance against other players and their own progress. Statistical data is collected from player scores and other factors and course adjustments are determined from a statistical analysis of multiple games played by multiple players at a given course. Player scores and other factors are normalized by statistically-derived average course factors such as course yardage and average approach length. Putting performance is also evaluated on a statistical basis to yield a putting average and individual putting grades. The method may be embodied in a server program providing access via an Internet website or may be embodied in dedicated terminals located at golf courses or golf shops.
