Here is a bar graph of the birth months for students in 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: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: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.
Note the percentages are close to this equation:Why Benford's Law pops up in financial data (like Apple's quarterly reports!)Fraud investigation with Benford's Law:Check out this website, Testing Benford's Law, for real actual data in action!Benford's Law with Recursive Rule dataGraphing Benford's Law with a Stat Plot.Press Y= and enter log(1 + 1/x). Press WINDOW and change Xmin, Ymin, and Ymax to these settings.Press GRAPH. Now press STAT to begin to enter data for plotting pointsHighlight L1, press CLEAR and ENTER. Move cursor to just below L1 heading and enter these numbers:CLEAR L2.Then enter L2 data.Enter the red numbers from the Benford Law's picture above into L2.The completed table has these entries:Press 2nd, Y=, 4, and ENTER to turn PlotsOff. Calculator states "DONE".Press 2nd, Y=, 1 or ENTER to access Plot1 settings.Press GRAPH to see both the equation and the points graphed together.Press Y= and CLEAR and GRAPH (or highlight the "=" in Y1= and ENTER to turn Y1 off).Simpson's Paradox with 1998 NBA Scoring TitleMichael 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?Notes on January 28, 2014.

Press 2nd Y= and enter the following settings:Press 1 ÷ 2nd 1 MATH 3 (or ^ 3) STO 2nd 3 to store 1/L1^3 into list L3.Press 2nd Y= and change Xlist to L2 and Ylist to L3. Press ZOOM 9. Press WINDOW. vPress TRACE to select a coordinate. To divide L3/L2 press 2nd 3 ÷ 2nd 2. Store into L6 to see all answers.Change Plot 1 back to original settings below. Enter new equation into Y1. Press ZoomStat again.If k = 39494, then A = 1/k = 1/39494 = 0.00002532030182. So y = 0.00002532 x^3.
