There are plenty of websites that try to characterize you based off a set of responses. Some surveys come via email and ask you to tally up your own score and see how you compare to the rest of the world. Some just try and answer a simple question such as what personality type or how happy or how outdoorsy you are. They’ll give 10 questions and based off how many you answer correctly, you fall into some category. Some more sophisticated applications may weight questions by importance and mathematically calculate a percentage that represents your characterization. For simplicity sake, I guess they do the job.
But here’s another idea…
One more method of weighting questions in a survey might be based off global survey or consensus results. For example, if I was to compute a score that asked, “How much of a Yankees fan are you?” two questions might be:
1) Do you hate the Red Sox?
2) Have you been to a game this year?
If a large survey was given, possible/expected results for these questions might be:
1) 99% Yes, 1% No
2) 20% Yes, 80% No
Based off these responses for a relatively large population, we can weight how much each question should factor in to the final result. For our example, since practically everyone hates the Red Sox, responding Yes should not play a majority factor in calculation of the final characterization. But since going to a game this year is a bit more of a rarity, perhaps it should contribute a higher amount to your final score. The trick is that for binary responses, you must denote which response increases the score and which decreases (it would be smart to gear the questions so that the affirmative case is always the increaser).
Taking this a step further, a lot of times the consensus of a larger group may not be known. In that case, your answers should become dynamic inputs to the weighting algorithm. They start at 50/50 and dynamically shift based on each new, incoming response. In a sense, the sensitivities are set by each new instance of that survey. Additionally, for non-binary / categorical / multiple choice responses, it would just require a bit more careful examination of weighting constituents.
Ill hopefully have an example of this weighted implementation in a near-future post.
Predicted Final AL East Standings (February 22, 2009)
Yankees 101-61 (62.35%)
Red Sox 95-67 (58.64%)
Rays 84-78 (51.85%)
Blue Jays 80-82 (49.38%)
Orioles 72-90 (44.44%)
Current AL East Standings (July 24, 2009)
Yankees 58-37 (61.05%) –> 99-63
Red Sox 55-39 (58.51%) –> 95-67
Rays 52-44 (54.17%) –> 88-74
Blue Jays 47-49 (48.96%) –> 79-83
Orioles 41-53 (43.62%) –> 71-91
The order is correct and collectively the winning percentages are off by an average of 1.00%. If calculating a final win count off current winning percentages, Yanks are off by 2 wins, Red Sox are exactly right, Rays are off by 4 wins, Blue Jays are off by 1 win, and Orioles are off by 1 win. Not too bad I must say… but reveal my methods? Hah!
The other prediction of Cubs playing the Yanks in the World Series may be a bit of a stretch, but they are only 3 games back in the NL Wild Card and are 5-2 out of the All-Star break. Still a possibility.
“A humble man of grace and dignity. A captain who led by example. Proud of the pinstripes tradition and dedicated to the pursuit of excellence. A Yankee forever.” – Don Mattingly’s plaque in Monument Park
i just wanted to throw out some predictions for this coming year in baseball. to start, here are three small reasons the yankees will win the world series this year.
1. the numbers
39 appearances (26 wins) in 106 years = in world series once every 2.7 years and a championship every 4 years. last appearance was in 2003. bound to happen.
2. the stadium
thing is awesome. no better way to bless the place than with a championship.
3. the young guns
more big names means deflected pressure and attention from cano, melky, damon, nady (if they are all still around for the year). if they can each put together some decent season numbers, the support is in place for those big names and the success runs full circle (or diamond).
Another thought: Cubbies make the World Series (but lose it to NYY)
