For those who see no reason to share the jackpot with someone less-deserving:

I believe something is wrong with this graph:

No, because the graph is only intended to show that the more people pick numbers under 31-- there are about 20 numbers not shown.

The bars are there for all of the numbers. The graph only displays the odd numbers as a way to keep the labels legible.

The article said something to the effect that the black line was based on computer generated numbers. If it were supposed to be a mean or median number, then, yes it would be too low.

isn't the black dashes line too low?

Looks about right to me. If 17000 people pick 6 numbers each, selecting from 1 to 45 then each number should be selected 17000*6/45=2267 times

Don, I think the numbers go up to 60-something.

This data set came from the May 3, 1996 drawing. At that time the numbers ranged from 1 to 45.

The article says that the "random" line was based on a similar number of computer generated picks, but I agree that that doesn't seem likely. Given that the reporter who wrote the article was probably not a mathematician, I would want to look back at the original report to verify.

Edit:

Here is a link to the Dartmouth Chance Teachers Guide, USING LOTTERIES IN TEACHING A CHANCE COURSE

[www.dartmouth.edu]

They did use the same size data set (17,001 picks) for the computer generated sample and the people-picked sample. The bar graphs look pretty much equivalent to the ones linked in OP.

So I am still puzzled by the superimposed samples, which should both contain 102,006 individual numbers. If the computerized graph represents 102,006 individual numbers, the people-picked graph appears to contain more individual numbers.

To put it another way, shouldn't the "area under the curve" be equal for both samples?

I believe "people-picked" numbers are mostly birthdays, so max month / day=31, so biggest occurrence in first 12 (month + day chance), then drop off to only include day (13-31), then another drop off beyond 31.

Just trying to get my post count up to get free money!!
