Mean sum of 6/49

[Bertil]

I've just posted my finding about hte mean sum of 5/55 at R.G.L ,and pointed
out that it is 148.5 after 196 draws, while the theoretical mean must be 140.
Also, the mean has been above 142 from the start and not fluctuated around 140.

Does anybody have any fresh stats for the mean sum of 6/49 over a long
period and if so, does it fluctuate around 150 or stay above all the time?

Lottery ball machines are an example of true natural randomness… So, someone may expect some mean sum (?) , or such “142” but it was “155”. That’s way it is random… That’s way people can’t know a future draw in advance….

People may fail at much easier tasks that even mainly include non randomness, but include a cause and effect… like predicting weather….you see in a newspaper it should be sunny all day, but hey, there is some rain….or opposite..

Sum of 649

You might have misunderstood my request. I'm not refering to individual sums
but to the mean cumulative sum after hundreds of draws. There is a table of sums at needto.com but I'm unable to download it so I need another table.

Sums for Canadian 6/49

After 2450 draws, the Canadian 6/49 has an average sum of 152.1 and it has been consistently higher than 150 for large number of draws.

The first 450 draws had an average of 152.6 and then, for each successive 500 draws, the average has been respectively 151.9, 152.1, 152.3 and 151.8.

The distribution of the sums is fairly normal and bell-shaped with a low of 45 (with numbers 01, 05, 07, 08, 11 and 13) and an hign of 263 (with numbers 38, 43, 44, 45, 46 and 47).

Everybody is expecting the famous 1-2-3-4-5-6 or 44-45-46-47-48-49 combinations to be comming out quite soon, maybe even in this century.

Thank you for info. It is interesting to note that the low sum 45 is 3.2 std.dev.units below 150 and that the high 263 is 3.45 std.dev. units above 150. The std.dev. is 32.8 from 150 for 6/49. Two std.dev. units would be 65.6
and I wonder how many sums were outside this limit.

Spread for sums in Canadian 6/49

Bertil,

Using your standard deviation of 32.8 and the theorical average of 150, here are some statistics for 3 ranges of sums:

From - To: - # of draws -- %
118 - 182: 1684 draws or 68.7%
085 - 215: 2354 draws or 96.1%
052 - 248: 2447 draws or 99.9%

Actually after 2450 draws, the average sum was 152.1 and the standard deviation was 32.2.
