Also, in seventh grade I took a typewriting class. Since school start I had turned in absolutely all the homework I could get away with in neatly typewritten form, while I got the impression that none of my classmates had ever even gone near such a wrting machine. I expected great things!
Alas, I flunked. The only one to do so, and hugely. I still typed better than anyone else, but I never got the hang of touch-typing. Sad to say, I haven't to this day. I seem to be stuck with the method developed by four year old me.
(If you want to give it a try, have a look at Colemak, I hear great things about it on HN every once in a while. Or Neo2 layout, if you need non-English characters.)
Also by now I have a keyboard that speaks dvorak natively. The Kinesis Advantage. Of course, that keyboard is programmable enough that I could make it speak custom layouts too, or just fix it in the OS.
That was a set of two LP records and a 20 page textbook printed on heavy card stock with a plastic ring binder at the top so you could open it tent style and read it as you listened to the record and typed along.
The first page was ergonomics: how to sit and how to type.
Then you learned the keyboard, row by row. The first two lessons covered the home row, followed by lessons for the top and bottom rows, numeric row, and finally shifting and advanced topics.
It was great fun!
I'll admit that a straight p-value is not the appropriate statistic here. I don't even know how what the perfect statistic for this problem is. A Bonferroni correction is not enough because not only is the 11th of the month the lowest for a particular year--it's the lowest for every year.
I was convinced that this was real when I looked at the first line graph of the post. The 11th is the lowest either every year or almost every year, being 3-5 standard deviations below the mean for the bulk of the last 200 years. That just can't happen by chance no matter how you slice it.
If anyone knows the proper way to calculate a statistic on something like this, I would love to hear about it.
