    SHould be really simple calculate of average

    http://arxiv.org/PS_cache/physics/pd.../0512143v1.pdf

    Click on the link then on the left hand column there is a table at the bottom.

    I want to calculate <games> which is the average number of games played by a team in a season.

    So i thought it would be :

    Highest Year - Lowest Year
    games

    But it's not, any help?

    Thanks

    The average is the average number of games played by a team in a season, so to compute this you need to know the number teams in each year and the number of games each played (which is 2(n-1) where $$ n is the number of teams in the leage and each team plays each of the others twice, which is true of FA I don't know about the others). The number of teams in each year is not the same so you can't deduce the number of teams from the total number of games and the number of seasons (which is S=\rm{Year}_{hi}-\rm{Year}_{lo}+1).

    May be you can derive \langle \rm{games} \rangle from what is given, but may be not, I have not checked.
