In this problem, we needed to find a way to use the Olympic medal tally in order to work out which country is the most athletic.
Joe and Matthew, from Chatham Grammar School, both considered the total number of medals which countries have won in previous Olympics. Matthew thought that because the 2008 Olympics contained the greatest number of events, the top five medal winning countries from this Olympics would be the most
Matthew then ranked these five countries according to the number and type of medals won using a weighted points system:
he gave $15$ points for gold, $10$ points for silver and $5$ points for bronze, and then divided the sum of these scores by the number of Olympic games the country had participated in.
