    Here is a bar graph of the birth months for students in period 5:

    birth months period 5  
    Are there any anomalies or things out of the ordinary?  Not really.  Nothing statistically significant.
    But consider the all star rosters of these youth sports teams:
    hockey birth months soccer birth months
    More athletes are born in the first months of the year than the later months, and by a huge margin.
    Consider the pie charts to analyze their relative frequencies:
     birth month pie charts
    Starting at the 12:00 o'clock position going clockwise, the larger slices belong to January, February, and March.
    This is statistically significant -- something is going on that affects this distribution.  But what?
    (see Stat Notes link near the bottom for the answer.  HINT:  It's from the book Outliers by Malcolm Gladwell.

    Simpson's Paradox with 1998 NBA Scoring Title 
    Michael Jordan had 2313 points in 81 games for a 28.6 average.
    Shaquille O'Neal had 1666 points in 59 games for a 28.2 average.
    For Shaq to win the scoring title, does he necessarily have to score more points in his final game?
    Shaq's career high in a game was 61, MJ's was 69.  The all time record is 100 points by Wilt Chamberlain.
    On the final game, Shaq scored 39 points but Jordan had 44.  What were their final averages?  Who won?
    As the new averages are 0.3 apart, but originally they were 0.4, this suggests Shaq can eventually score fewer points than Jordan but still have a higher average.  What amount of points demonstrates this paradox?
    Find what amount of points results in a tie, and the tying average.  
    If they each score 98 points, what are their averages and who wins the title?
    If they each score 99 points, who wins the title with what average?
