Red Advantage ?
 

Does the Red alliance have an advantage over the Blue?

George Williams (60) asked my dad if he had noticed that the red alliance had an advantage over the blue in the finals at the Sacramento Regional. He went on to say that he noticed blue only won two matches during the finals at that regional. George’s thought was that the red tetras had better visual perception than the blue tetras. My dad and I decided to put a spreadsheet together to determine if this might be true. We took the final's match results from each regional that FIRST posted on their website. Not all of the results were posted, so we used the data that was available as of the evening of 3-12-05 6:00 pm MST. We put the data into our spreadsheet to analyze it. We did notice that there are discrepancies in the team numbers and we can only assume that the scores are correct. Based on this information it looks as though the red alliance does have at least an 18% advantage over the blue alliance.

If anyone has new or corrected data please send it to me at Krystinet@hotmail.com. I will continue to update the spreadsheet as more data becomes available.

that makes sense since red is a warm color(see i payed attention in art class) it stands out more than blue

Re: Red Advantage ?
 

I think this assumption is just a feeble human mind trying to find some sort of correlation in truly random events, like saying your iPod is playing favorites while on shuffle mode. :)

Re: Red Advantage ?
 

Is it possible the "advantage" is because the higher seed is generally red?


Edit:
In the first round, the 1st, 2nd, 3rd, and 4th seeds are red, and the 5th, 6th 7th and 8th seeds are blue. In the semi-finals, the 1st and 2nd seeds are red (or the 7th or 8th seed if there was an upset), etc.

Re: Red Advantage ?
 

Coincidence I think. Also, can you fill us in on what happened using the Phoenix update thread?

[edit]I just saw that you're on team 254, but I know who your dad is and I know he's on team 60, so now I'm confused[/edit]

[edit 2]Don't trust the results from Phoenix either, because they're mostly incorrect/backwards[/edit2]

Thanks,

i think its just a matter of how well the eye can spot certain colors from far distances, and line up their robots with it.

Agrees with Joe Ross.

As coach for our drive team, I certainly didn't notice any perceivable difference between the two sides, save the giant real time scoring system(but it wasn't working at all during FLR). Perpahs you should compile all scores from regionals and then analyzed them for descrepancies.

Re: Red Advantage ?
 

Pulling out my calculator and doing a quick 1-proportion z-test, if the true proportion of red wins is 50%, then this observed proportion of 62% would occur 0.7% of the time. Thus, we can conclude that something is up.

I agree that red alliances are often higher seeded alliances and may play a large part.

As a driver and member of a team whose color is red, I prefer red to blue.

Re: Red Advantage ?
 

I'll agree with Joe. If this discrepency is this large in just the quals, then it might mean something, but the elims are obviously not a truly random sample. I think you'd need a bit large sample size as well to actually conclude something.

Re: Red Advantage ?
 

A bigger sample does not make it any more random. This cluster sample of elimination matches is (and can be) assumed to be representative of all elimination matches.

Re: Red Advantage ?
 

In the elimination rounds (QF,SF,F) the scoring system places the higher seed alliance in the Red Zone, so one should expect better results. In fact, if the results were equal between Red and Blue (50/50), then the Blue End would have an advantage.

Re: Red Advantage ?
 

But Kevin's point is that the choice of colors in the eliminations is not random. All that has been proven is that higher seeds have an advantage in the elims, not that a certain color has an advantage.

Re: Red Advantage ?
 

I don't know if this matters but our team at the st. Louis regional preferred the blue side.

Re: Red Advantage ?
 

You and Kevin are correct, the highest seeded alliance is always placed in the red zone by the computer. In fact, its a great communist conspiracy to mold the mind of teenagers into equating Reds with winners. (They tried with baseball but this lost effectiviness decades ago). Interestingly enough, at GLR in the QF's Blue won 50% including the most improbable Alliance 1 vs 8.

No, it's a Republican conspiracy. :eek:
