If you group the results of football matches by goal difference the seem to be following a bell-type of distribution which is slightly skewed in favor of the home team. The following applet allows you to check on how each of the Teams in the Premiership fared agains another one in the seasons 1993-2011. (These are Premiership matches only, not FA Cup, Champions League etc.)
Blue are home team victories. Red are visitors’ victories. The small number in the corner of each rectangle represents the number of games.
