Think you might be confusing sample standard deviation with standard deviation.

Your gazillionth flip would have the same expected standard deviation as any individual flip because that particular flip is exactly one flip. This is also true of your 12th flip.

Yes. Thanks. I didn't realize until I asked the question, that there was a difference.

I think BTM is essentially correct, though his analogy is tricky. Consider this:

Quote:
It is very important to note that the standard deviation of a population and the standard error of a statistic derived from that population (such as the mean) are quite different but related (related by the inverse of the square root of the number of observations). The reported margin of error of a poll is computed from the standard error of the mean (or alternatively from the product of the standard deviation of the population and the inverse of the square root of the sample size, which is the same thing) and is typically about twice the standard deviation—the half-width of a 95 percent confidence interval. In science, researchers commonly[citation needed] report the standard deviation of experimental data, and only effects that fall much farther than two standard deviations away from what would have been expected are considered statistically significant—normal random error or variation in the measurements is in this way distinguished from likely genuine effects or associations. The standard deviation is also important in finance, where the standard deviation on the rate of return on an investment is a measure of the volatility of the investment.
Your win rate is always going to have a significant deviation that is inherent to the game. Even if you play a billion hands, you'll have losing sessions and heaters. The more you play, the more your sample standard deviation will match the "true" deviation that you'd get if you played infinite hands.

Ok, thank you. If I ever disagree with BTM, I know I'm in big trouble.

When I tried to envision the distribution curve in my head, I convinced myself that the standard deviation remains 40. What am I doing wrong? I looked up the algebraic formula and there seems to be a square root in the denominator with N snuggled into the square root. By looking at a formula, I get the impression that standard deviation decreases logarithmically as the sample increases. Can someone please help me to envision why this happens in geometric terms? I would try to project what's going on in my head onto this post, but I'm afraid that if anyone saw what was in my head, they would go insane.
Thanks.
If your actual sd/100 hands is 40bb then your sd/2000 hands will be about 180 bb (sqtr[20] * 40 ). While your (win rate)/2000 hands will be 188bb (20*9.4). As the number of hands goes up the sd/(hands played) goes up in terms of bb's but goes down as a percent of (win rate)/(hands played). And it goes down as a percent of the number of hands played ( 188/2000 is less than 40/100 ).

However, your PT4 is not giving you your actual standard deviation or win rate. It's calculating a statistical "sample" standard deviation and win rate based on your results to that point. It's an estimate that the PT4 will update as you play more hands. But as you play more hands, even though the PT4 bases it's calculations on more hands it's not giving you a "per hands played" calculation. It's giving you a "per 100 hands" calculation. It's not changing what it's trying to estimate.

Is online poker even feasible from low-ranked spots like Alabama anymore? Too much responsibility primary parenting to even have time to travel for poker these days. Play some Race For the Galaxy for the card art though alone.

I'd say especially the first strike is problematic. The one making the first military strike gets the blame, and the action may destabilize other nuclear nations. This is in the end still mind games and speculation. I think the only possibility is to see if NK really does something lethal. Then the option to strike back is there.

The quoted video is from 2013. He could have become more pragmatic for example, slowly learning something. We don't know surely enough, at least not in the eyes of the world.

It is strange to even consider "wiping Seoul off the map" as the important thing to consider. No one with a modicum of sense is expecting the entire peninsula to fall into the ocean. The concern is massive loss of life and large scale economic disruption.

It's not dependable like it once was. Ignition is a soft site but with awful software that crashes frequently and no rakeback. WPN has decent rb but is reg infested. And those are about the only sites that are U.S. facing that I trust or that have any volume.

You cant wear that!

But you can wear this;

The day racist lives matter to change is the beginning of the end for racism.

(you can split in 2 sides)



Most racism exists because people are lazy to do the work. The work wont involve shunning but reasoning and example.

First form of laziness is the lack of desire to read a detailed quote t-shirt. lol

Sure you can. What's more, it's a very moral and correct thing to do - to force people to confront their hateful prejudices against nonviolent ideas they dislike.

Ordered the print already for a few shirts. Might pay some homeless people to wear them.

Hmm.

Perhaps one culture, one ethnicity, one language, all encompassing the best of the best is the end game. I don't know.


One has to step enough back to grab a wide view of cultures. To see there is already and always will be one human culture which includes all the distinctions and multiples. Our 'meta-culture' is vast and diverse as our planetary ecosystem. We have indeed grown closer and less alienated- by struggle and facing challenge ...the game continues.

Sample standard deviation if you use over a few thousands hands for sample i bet remains the same for most players more or less. Sure its a random variable itself but its not going to be very volatile (it reflects your game and type of opponents you select to have). Only by changing your game and number of opponents in a table this changes seriously because you play more loose or tight depending on situation.


But the important topic here was the standard deviation of the end result of millions of hands not the variation of the sample standard deviation.

When you add random variables that have the same sd the sum itself (the sum of all outcomes is your bankroll change) becomes a random variable and its own standard deviation is now (your bankroll's standard deviation after that many hands) n^(1/2)*sd ( sd is the historically established by extensive sampling sd per hand).

I think it was Paul McCartney who said it best with, "We all know, that people are the same wherever you go."

There's a fundamental truth to that, but it's deep down and you've got to ensure there doesn't include some conflicting ideologies. Yet, it's even more complicated.
I work with people from Pakistan, India whom speak the same language yet have different names for it - Urdu or Hindi. Folks from African, Caribbean and eastern European countries. And we are all the same.

It's only on the superficial level, where it's interesting, subjectively. We talk differently, we enjoy different cuisines, etc.
But just give it one, two, maybe three generations tops and that superficial appeal is no longer.
