Footy Tipping Case Study
Many organisations (like the School of Computing and Mathematics) run a football tippingMarketing Research and Data Analysis
competition. The basic objective is for a person (called a tipster) to tip or pick the winning
team in the games in a football competition. The objective of this system is to support an
organisation in running a tipping competition.
The system needs to support all codes of football including Soccer competitions and
Australian Rules competitions. Soccer Games are simply scored on the number of goals
obtained by each team. Each goal has a value of 1. Australian Rules football is scored
using goals, behinds and points. For example a score of 10.9.69 reads as 10 goals, 9
behinds, 69 points. The points are calculated from the formulae:
points = goals x 6 + behinds. Eg 10 x 6 + 9 = 69
The following page contains a two rounds of football with the results taken from the year
2000.
A sample entry is shown below. The home team – Richmond in this example is always the
first listed team.
