Stats, stats and more stats

I can’t help myself. I love stats. What could be more fun? I look at them endlessly because they are endless. Sometimes I make my own stats out of stats I see. Sometimes I find myself reading stats of things I don’t even care about. Below are the tiniest smattering.

What states have the best average Sat scores as of last year?

     State           Math                Writing            Combined

1   Illinois        599                  617                  591

2   Minnesota  593                  608                  577

3   Iowa           596                  606                  575

4   Wisconsin   590                  602                  575

5   Missouri     592                  593                  579

6   Michigan    583                  604                  574

7   N. Dakota  586                  612                  561

8   Kansas        590                  595                  567

9   Nebraska    585                  591                  569

10 S. Dakota   584                  591                  562

You might notice that they are all Midwestern states.

Try the worst. D.C. is included, and, as we know from the news, last. Notice that most of them are on the east coast and in all cases, coastal.

     State           Math                Writing            Combined

42 New York  485                  499                  476                 

43 Nevada       494                  496                  470

44 Delaware    489                  490                  476

45 Hawaii        479                  500                  469

46 Florida        487                  489                  471

47 Texas          479                  502                  465

48 Georgia      485                  487                  473

Switch to football. Drew Brees threw more touchdown passes than anyone in the NFL last year – 46 to Aaron Brown’s 45. But, per attempt, Brown blew him away.

QB                  no. of tds         tds per attempt

Aaron Brown  45                    .089 or almost 9 per 100 throws

Drew Brees     46                    .070 or 7 per 100 throws.

Compare that to the year before – 2010 season

QB                              tds per attempt 2011   tds per attempt 2010   Improvement

Aaron Brown              .089                             .058                             53%

Drew Brees                 .070                             .050                             40%

You think that the new rules protecting the quarterbacks and receivers had anything to do with it? Let’s look at the top ten quarterback passing ratings for the last two years.

QB                              2011 rating                  2010 rating

Aaron Rodgers            122.5                           101.2

Drew Brees                 110.6                             90.9

Tom Brady                  105.6                           111.0

Tony Romo                 102.5                              --.--

Matt Stafford                97.2                              --.--

Matt Schaub                  96.8                             92.0

Eli Manning                  92.9                             85.3

Matt Ryan                     92.2                             91.0

Alex Smith                    90.7                             82.1

Ben Roethlisberger       90.1                             97.0 (and he played hurt for a while)

Philip Rivers                  87.7                           101.8

Matt Moore                   87.1                             55.6

Black – improved rating         red – lowered rating

Only two qb's had better seasons the year before – for Tom Brady, who always performs so well, it almost doesn’t matter (1st in 2010, 3rd last year) and Phillip Rivers, who was sensational the year before (2nd) and so bad, comparatively, this last year that there were articles about what happened to Phillip Rivers?

I skipped the 200 meters because there wasn’t a record in the early 20th century. The interesting thing is to notice the relatively small band of improvement in all four races - all of them roughly around 10%. I wonder what would happen if we take the records for a plane and a car what the improvement would be. Obviously, it has to be a lot more as technology improves a lot faster than evolution.

4 wheel driven land speed record - MPH

*still the record today over 60 years later. Interestingly, when they tried in 1989 – the jet era, the fastest propeller plane was a little slower than the fastest almost 30 years before. But, this is because we’ve moved on in what we concentrate on.

In other words, our fastest runners have improved a fraction in a hundred years but technology has propelled our vehicles over three to five times faster – 3-500 percent over a 100 years. Of course, if I included jet or rocket propulsion, the speed of vehicles, land or air, goes up dramatically – particularly in the air.

Geography

– people per sq. kilometer

Monaco – 16,025 (total number of people is about double that)

Mongolia – 2

- largest islands

Greenland

New Guinea

Borneo

Madagascar

Baffin (Can.)

Sumatra

Honshu (Jap.)

Great Britain

Victoria (Can.)

Ellesmere (Can.)

Greenland, the largest, is roughly 11 times the size of Ellesmere, the tenth largest.

-tallest mountains by continent

Asia – Mount Everest - 29,035 ft. *

S. America – Aconcagua – 22,831

N. America – Mount McKinley 20, 320

Africa – Mount Kilimanjaro – 19, 563

Europe – Mount Elbrus – 18, 481

Anarctica – Vinson Massif – 16,066

*By convention, and as every kid knows (at least in my day), Everest is the tallest mountain in the world. But, Mauna Kea, Hawaii, sits partially in the water and from its base is much taller – 33,476 ft.

Religions in America (Pew)*

Christian – 78.4

Other religions – 4.7

Unaffiliated – 16.1

Further breakdown by religion

Christian – 78.4

            Protestant – 51.3

            Catholic – 23.9

            Mormon – 1.7

            Jehovah Witness - 0.7

            Orthodox - 0.6

            Other Christian – 0.3

Other religions – 4.7

            Jewish – 1.7

            Hindu – 0.4

            Other** - 1.7

Unaffiliated – 16.1

            Atheist – 1.6***

            Agnostic – 2.4***

            Secular unaffiliated – 6.3

            Religious unaffiliated – 5.8

Refused to answer/don’t know – 0.8

*Some might argue as to where certain small groups belong. E.g., many Christians claim Mormonism is not Christianity. Mormons disagree. Ditto, some Orthodox Jews claim Reform and Conservative Jews aren’t Jewish, although this is more an issue in Israel than in America. But, Pew went by what people say they are.

** Lumping in other world religions and things like Unitarians.

***Other studies show a surprising number of those who call themselves atheists or agnostics also say they believe in God. So, you might split them up in the religious unaffiliated group too.

Unaffil.           23                    55                    15                    8

*Or leans that way. That’s a pretty stark divide and one of the best predictors of political beliefs. Mainstream religious – more likely Republican; minority religious or unaffiliated – more likely Democratic.  Other than Jeh. Witness, who tend to be more independent (possibly apolitical is my guess), independents were fairly even across the board, with Muslims and Hindus being a little more likely than others to be so.

Good enough for today. Go read some stats.

  1. Two issues: on the SAT's, how can the average combined scores be so much lower than the average scores in each area? If the ave math score is 400 and the ave verbal score is 600 then the ave combined score should be 1000. Since the national average score is in the 900's something is off in your combined scores.... Secondly, football - Aaron Brown was a nondescript back up QB for the Giants. He never threw 45 td passes in a season. Did you mean Aaron Rodgers???

  3. Bear: I know (SAT). Those are the scores though. I found them on two sites and did not look into it to understand the scoring.

    On Aaron - aaarghh. I always call him Aaron Brown. I used to know an Aaron Brown and I can't get it out of my head even with that commercial where the cheesehead screams out RODGERS!!!!!

    Oh, well. If I don't make a typo, it means I have too much time on my hands. Which brings me to -

    Anonymous - Yes. I was thinking the same thing.

About Me

My photo
I started this blog in September, 2006. Mostly, it is where I can talk about things that interest me, which I otherwise don't get to do all that much, about some remarkable people who should not be forgotten, philosophy and theories (like Don Foster's on who wrote A Visit From St. Nicholas and my own on whether Santa is mostly derived from a Norse god) and analysis of issues that concern me. Often it is about books. I try to quote accurately and to say when I am paraphrasing (more and more). Sometimes I blow the first name of even very famous people, often entertainers. I'm much better at history, but once in a while I see I have written something I later learned was not true. Sometimes I fix them, sometimes not. My worst mistake was writing that Beethoven went blind, when he actually went deaf. Feel free to point out an error. I either leave in the mistake, or, if I clean it up, the comment pointing it out. From time to time I do clean up grammar in old posts as, over time I have become more conventional in my grammar, and I very often write these when I am falling asleep and just make dumb mistakes. It be nice to have an editor, but . . . .
