2010 Team Report Cards

I thought it might be fun to analyze how teams in our league did, relative to one another. Using this handy calculator, I calculated the standard deviation for each scoring category in our league and assigned each team a letter grade.

This section is for anyone interested in more detail on how the letter grades were assigned. As I mentioned above, I calculated the standard deviation for each category individually. The letter grade assigned is based on the distance from 'average' a teams category value is. You'll notice that there are more 'C' grades than anything else in the table. 



The list below represents how grades were assigned:
  • A: >= 1 standard deviation above average
  • B:>= 0.5 standard deviation above average
  • C: < 0.5 standard deviation above average 
  • C: < 0.5 standard deviation below average
  • D: < 1 standard deviation below average
  • F: >= 1 standard deviation below average

Here is the raw data for the average and standard deviation value for each scoring category:

  • G: 351.71429 ave, 53.06254 std dev
  • A: 579.78571 ave, 72.16467 std dev
  • +/-: 12.92857 ave, 57.30553 std dev
  • PPG: 100.42857 ave, 19.50353 std dev
  • PPA: 187.35714 ave, 34.07892 std dev
  • GWG: 54 ave, 11.53875 std dev
  • SOG: 3493 ave, 388.05909 std dev
  • HIT: 1795.57143 ave, 259.31468 std dev
  • DEF: 171.92857 ave, 34.28757 std dev
  • SHP: 17.14286, 4.25706 std dev
  • W: 63.64286 ave, 15.09781 std dev
  • SO: 8.78571 ave, 2.11047 std dev
  • GAA: 2.607 ave, 0.16426 std dev
  • SV%: 0.91267 ave, 0.00497 std dev




Here's an example of how grades were assigned for the goals (G) category based on the above data:
  • A: 404.77683 or more goals
  • B: between 378.24556 and 404.77682 goals
  • C: between 325.18303 and 378.24555 goals
  • D: between 298.65174 and 325.18302 goals
  • F: 298.65175 or less goals
