6/49 Discussion For May 28

But what will happen to the beer, if they discover that the malts and barley have been sprayed by a carcinagin pesticide, will the sun still shine then?

 

[Dennis Bassboss]

Hey Lucky Strike, I don't think you would offend any of us out here, we're still all eatin' beef, thanking God we can eat with out masks on, mind you those damn mosquitos, and that west nile thing makes you thirsty for a cool pint of walkerton water. Life has gone to **** and a hand basket, can't enjoy any of lifes pleasures, without worring about something, thank god they got rid of colored toilet paper, so we don't have to worry about rectal cancer.
Next thing you know the'll find something wrong with Atlantic Lobster, I can't bear the thought!

The mosquitos were going high this week....and so am I...As simple as that....And thank god that they are not affected by this Nile virus stuff otherwise..I would look like a mummy by now...

My analysis shows the following:
Using the last 50 draws and the 6 main numbers.

1. The Sum of the 6 numbers is 177 & SD 27.4 ===> -1s=150 -- +1s=204
2. The Average Sum is 25.3 & SD 3.9 ===> -1s 21.4 -- +1s 29.2
3. The Standard Deviation of the 6 numbers is 14.89 & SD 2.81 ==> -1s 12.1 -- +1s 17.2


Any observation/critique is welcome.

Nick

The average SUM of 177 appeared not likely so I checked your data. I get some quite different results on the last 50 draws for SUM, AVERAGE and STANDARD DEVIATION.

I can duplicate your results when I use all 7 numbers (including the Bonus number). But you say that you used "the 6 main numbers".

Would that affect your analysis if the data is based on 7 not 6 numbers?

 

[peter]

Could someone explain in clear detail, what standard deviation is?. Thank-you, Peter,
P.S. and how does it relate to the lottery, and what does it all mean? and how would I use that information.?

 

[GillesD]

Standard deviation

The standard deviation is a measure of variation.

If your data is all in a very small range (let's say the average of the 6 numbers for 10 draws are all between 24 and 26), then the standard deviation will be small. But if the averages are between 20 and 30, then the standard deviation will be much greater.

Basically it is a measure of the differences between individual values and the average of all values with more weight given to those far from the average.

Based on the first 2018 draws, the average of the 6 main numbers is 25.4 and the standard deviation is 5.4

For a normal distribution, you could expect to have 68.3% of the averages between 20.0 and 30.8, or 95.5% of the averages between 14.6 and 36.2 or 99.7% of the averages between 9.2 and 41.6.

Actually what you have is:
67.8% between 20.0 and 30.8;
95.9% between 14.6 and 36.2;
99.8% between 9.2 and 41.6.

 

[Rebeckah]

So how would you figure out the standard deviation of something?

 

[GillesD]

Standard deviation

If you use Excel or an other software that provides statistical analysis, there usually will be a function to calculate the standard deviation. In Excel it is STDEV(data).

Otherwise it can be calculated by the formula:

Square root of the sum of the square of differences between individual values and the average of all data divided by the number of data minus one.

Well, using Excel might be easier.
