Could you post the data as an ogive?

Can you post a chart for MSC only as a comparison?

Yeeeeah. MSC was a whole different game. The competition level was unmatched, the only regionals that even got close were Waterloo and GTRWest, and they don't even hold a candle to it.
Way to go Michigan!
D is for Data, that's good enough for me...

That last graph is a bit deceiving since you took the 'all events' line off.
Visually, GTRWest+Waterloo look like they match the 'all events' line, relative to MSC, but in actuality, they're quite a bit stronger if you look at the numbers.
The graphs are interesting though.
Unsurprising that GTRW/Waterloo are very similar (both late season, both in the same geographical region, and both with MANY of the same teams).
Whats interesting to me is the slope differential. MAR seems to have a taller slope (which I believe equates to a narrower band of 'average' scores, meaning tighter competition), but the top end lines up with GTRWest and Waterloo fairly well, while MSC is stronger.
I think that would suggest that GTRW/Waterloo/MAR all have fairly similar max-score (which I would say is primarily a function of the 'best 2' robots), while MSC is higher throughout the curve. It also suggests to me that MAR's midrange teams are on average stronger, which makes sense, since its an invitation only event.

Pretty cool/relieving to see the data support that MARC was a tough event. Not as tough as MSC, but also there are about half the teams in the region, so the competition won't be quite as high at MARC. Until this point, MARC was receiving a lot of criticism for well known teams declining to attend. I also couldn't help but notice that the game strategy in the region was a little different than every where else due to the defensive, rough-and-tumble nature of many teams in the area. Motors ran hot at the conclusion of each match.

I think the data actually suggests that max match scores at the Canada events were higher than MAR (b/c of aforementioned teams), but there was a faster drop-off in competition after the top teams. Whereas MAR had lower maximums and consistently higher average scores as you said. The lack of many floor pick-up bots, and fast 30 point climbers kept max scores in check. Matches were shoot 'til you die, and if you can't cycle 4 times, you can't keep up, so play defense. In nearly every elim. match, at least one side went through all white and colored discs at the loader station.
A histogram may answer some of the questions.

Well, that 171 score in MAR is ours...and we lost that match :ahh:
Thank you Ether for posting all this data.
Would it be possible to report on winning match scores only?

Do you mean a histogram of alliance winning scores?
Yes. Histogram and ogive. It's interesting to put the data for all the alliances and just the winning alliance scores on the same graph.

Check back later this evening. I'm pulling the wheels and inspecting the brakes on my daughter's car right now.

Never seen this before. Does anyone know how to get the hubcaps off a 98 Chevy Lumina? The "lugnuts" appear to be plastic. Old-fashioned prying of the hubcap rim doesn't seem to be the solution, so... are those plastic "lugnuts" holding the hubcap on? And if so, am I supposed to pry them off or screw them off (and if so, left or right?).
If it were my car, I'd just put a tire iron on it and find out. But it's my daughter's car...
GM had a few years where the plastic lugnuts screwed onto the real ones underneath. Try a soft set of vise grips to unscrew the plastic ones. Is there a lugnut key in the glove box somewhere, too?
unscrew the plastic ones
are the threads left or right handed?

See step 6. http://www.ehow.com/how_2314153_change-flat-tire-1996-chevrolet.html
Well I followed Step6 and broke the plastic nut off. Underneath it was what looked for all the world like another plastic nut.
Life was a lot simpler with my 67 Impala, 68 Camaro, and 72 LeMans.
I'm curious, what was the high score for all matches?
Todd, is this what you had in mind? I can change it if not.
I had in mind "wins" and "all".
You will see why in a day or so...
I had in mind "wins" and "all".
Do you want "all" to be "wins+losses" or "wins+losses+ties"?
Do you want the Y axis to be a percentage or a number of scores?
3216 red wins
3127 blue wins
60 ties
----
6403 total matches
"all" = "wins+losses+ties"
Y axis to be a percentage
Y axis to be a percentage
Would you like it to be a percentage of:
1) all/all, and wins/wins, or
2) all/all, and wins/all ?

Crossroads seemed to be a high scoring event, especially elims.
Can you add it to the histogram with the few other events?

Just out of curiosity, what software tool are you using? I just had a class in mathcad, and am developing a tool to predict match scores. I'm using your data from this year to check it.

Chris, you might be interested in Jim Zondag's plot that compares all events both in average OPR and in competitiveness (standard deviation of OPR). http://www.chiefdelphi.com/forums/showpost.php?p=1261860&postcount=21
1) all/all, and wins/wins
OK, see attached.
Just out of curiosity, what software tool are you using?
AWK scripts: parse/sort/select raw data and perform simple math
RLaB or Delphi: all the linear algebra stuff for least squares (e.g. OPR etc)
Excel and/or gnuplot: charts & graphs

One more refinement... Can you change the units on the histogram from percent to number of matches?

To make the ogive graph from post #35 even more interesting, could you add the (L+T) ogive?

Does anyone have the Qual Match Results data for 2012 or earlier years in a delimited, fixed-field, or CSV text file? I've had a request to post some comparative graphs for previous years but I don't have the data handy.

Do you mind making a championship version of this? I'd like to see how much champs is better than this. Thanks!
Do you mind making a championship version of this?What does the pronoun "this" refer to? There are many different charts in this thread, and there's no context in your post available for disambiguation.
Attached is an ogive of CMP vs MSC for comparison.

My bad, I was wanting to see CMP vs week 1-7 as an ogive, although the graph you posted is very interesting. thanks!
What software do you use to make these graphs?

How about the events in Texas-Louisiana vs. MSC and overall
Alamo
Bayou
Dallas
Hub City
Lone Star

Am I reading this that MSC was at the 50% level 30 points per alliance higher than the Championship? At the 90% it was almost 20 points higher?
