A score is registered when the ball crosses the end-line and between the two uprights as illustrated below. Gaelic games are a little different to other sports in these requirements as I have explained previously (here). When the ball crosses the end-line, between the uprights, and above the horizontal bar then the team gets a point. When it crosses the end-line, between the uprights, and below the horizontal bar then a team gets three points (called a goal). I'm guessing that the reporting of both goals and points is a relic from the early years of the GAA when the team with the most goals won the game and points only counted when teams finished level on goals.
For the 11 games I examined, the ball crossed the end-line 3.7% of the time for a goal, 58.2% of the time for a point, and 38.1% of the time for a wide (or no score). I cheated a little by presuming an equal number of shots went left and right of the target. This is approximately 1.63 scores for every wide (of course some scores are worth three times the value of other scores).
Knockout competitions made it very difficult to make comparisons between teams. A huge difficulty arises because teams play different opposition. There is also a difference in the number of games teams play, e.g. those knocked out earlier tend to play less games. This is why I want to focus on games rather than teams. Figure 1 presents the total points score accumulated in each of the 11 games examined where three points are awarded for each goal. The points arising from goals is shaded in green (the colour of the flag raised when a goal is scored).
There is an average of 46 points per game. This is made up of an average of 2.45 goals per game and an average of 38.64 points per game. The distribution of goals and points across the 11 games is given below.
