Disc Golf Course Ranking Terms
What does all this mean?
- Rating - The course rating is derived from the average
strokes per hole for a disc golf course. Only courses with at least 2 active
players with at least 3 rounds played each will be rated. An active player
is any registered disc golfer that has entered a round in the last 180
- Standard Error - The standard error is a measurement
of the statistical accuracy of the course rating based on the sample
size used to obtain the rating. A lower standard error value indicates
the rating is more accurate. A high standard error indicates the ranking
is less accurate. As the sample size increases with more players adding
their scores, the variation between the samples should decrease, and
the ratings should become more accurate. In general, the disc golf
course rating is more accurate when there is a greater sample size
at that disc golf course. Only averages from players with at least
3 rounds scored for a course are used. If a player hasn't entered
any rounds in 180 days, their average is not used.
- Standard Deviation and Variance - The standard deviation
tells you how evenly the values in a sample are distributed around the
mean (or average). This measures how varied in skill the disc golfers
are that were sampled for a given course. A smaller standard deviation
value indicates the sampled players are closer to each other in skill.
A greater standard deviation value indicates the sampled players were
of mixed skill levels. A high standard deviation indicates that the players
at a given course have a great variety of skill levels. A higher standard
deviation increases the rating accuracy. A lower standard deviation decreases
the accuracy. For example, if the sample contains scores from only pros
(or only beginners), the standard deviation would be low. The pro scores
would be low making the course rate easy while beginner scores would
be high making the course rate hard. A beginner comparing one course
to the other would mistakenly think their course is harder than the pro
course and vice versa.
Why doesn't my disc golf course show up in the ratings?
Only Courses with 2 or more active players will be ranked.
If your course doesn't show up, try recording the scores of the people you play with or encourage them to enter their scores.
