Reminder - Hockey Ticket Preregistration

[canuck89]

1.  2004-2005 was a lot better than last year.  Less than 100 people were waiting around on central for the annoucement; all others came running/driving like crazy.

2.  Yes, last year should have been done on Saturday with more facetimers out partying and such.

So?  The 2005 system was almost identical to the one of 2004, however, then the system was new and students didn't know what to expect.  The following year had 2000+ people waiting on central.  Even if tickets were distributed at the vet school (B-lot), this would have been completely unmanageable especially if it had been outside (Would people act orderly in that situation too?).  The perfect system does not exist.  Something will have to be sacrificed -- academics, safety, or even rewarding the most dedicated fans.  We can only hope that soon athletics will realize the last one is as important as the other two, though.

WHAT ARE THE GODDAMN ODDS THAT I WOULD BE BETWEEN 1051 and 1476?


sorry. I'm going to go drink now. anybody with tickets, you know where to send'em.[/quote]25.33%[/quote]
On the other hand, if your number was, say 1250, if the drawing was as explained, which assumes that once a 1 was drawn that the 7 through 9 were then removed from the pool for the 2nd number (as opposed to leaving them in and then if 17xx was drawn do the entire drawing over) your odds of losing were 32.1% rather than the fair 25.3%.

[quote imafrshmn]In case anyone was wondering, the drawing method was not perfectly fair.  The total number of entries in the undergrad line was 1674.  They chose the starting number digit by digit.  This would have been fair if there were 1999 entries.  However, when there should have been a greater chance of starting the line with a number below 1000 than above, their system gave both numbers a 50% chance (they were basically pulling numbers from a hat, it seemed).  So, the starting number was higher than it should have been in a random system.  The result of all this is that the line numbers in the low 1000's were at a disadvantage to "win", while those with numbers in the low 0---'s were at a bit of an advantage.  If anyone knows how to calculate the exact degree of the effects of the drawing system on selection probabilities, that would be interesting.[/quote]

Real Good numbers, 1674, 1-575 have 78.8% chance of success
(note: can't lose if 1 drawn first, 42.4% loser if 0 drawn first)

Real Lousy number, 1250, 67.9% chance

Wow, they can't even pull a random number correctly.

Wish I had taken the time to figure out all that math BEFORE I decided it didn't matter when to get my ticket (and thus got both a lousy regular number and senior number). After all the hype about how all numbers were the same, I got mine near the end out of convenience. Damn ILR for not teaching me proper statistics...

not your fault if they didn't give each number an equal chance -

Are you actually sure they gave both zero and one equal chances of being drawn for the first digit? I was under the impression they just chose one of the full, preregistered numbers at random (not using a digit by digit system). Or alternatively they could have had 8 zeroes and 4 one's, for example in their drawing pool for the first digit.

They chose digit by digit.  A lot easier to do that than have 2000 printed numbers to deal with.

[Cactus12]

So they actually chose in front of everyone?

[saff678]

From what it looked like, first of all numbers were drawn in front of everyone in the center of the football field, not in the press box.

Second, it appeared that the first undergrad number drawn was the 2 digit number 14, so presumably it was picked from a pot of 00-17.

[elcielo917]

i agree. if you were there, the first number was called as "14" from a single piece of paper. it certainly seemed like they drew the first two digits together, presumably from a pool of 0-16 or 0-17 or whatever, thus elimintating all this talk of unfairness.

[Cactus12]

As I presumed. Thanks for the clarification.
