Default Compiled Small Stakes stats

Hey all,

attached is a preliminary post of the stats from the 2/4 and 3/6 games.

I wanted to do a little more (I also still have to post the correlations), but I also wanted to post this sometime today.. and I'll be running from 9-10 or so, I'll just kinda put this out there now...

There are a few interesting things I'd like to point out... but I'll probably have to wait until tomorrow

This is sort of a rough draft... and I would appreciate anyone's input as to what might make it better.

Big questions:

a) Anything that seems like a typeo?
b) Layout? Is it clear? Im not great with that kinda thing.
c) What do you think of the 0.5 SD range? That was an arbitrary choice. It is flexible...

EDIT: I am interested in keeping this going... so, I will keep the info stored in an splus file on my comp, and would be willing to add to the ball, and update once every 2 months or so.

Default Re: I hate you tiger woods.... AKA: Stats post

Introduction:


The intent of this post is NOT to have players change their game in an effort
to make their stats look more like those presented.

This post is intended to give people who are curious about their stats an idea as
to where other winning players stand. The one-half standard deviation range about
the mean is probably a good range for your stats to be in.

It is very likely that winning players exist whose stats fall outside of many
or all of these ranges. Likewise, it is very likely that some losing players
have stats which fall within all of these ranges.

Stats are great for plugging large leaks. If a player has a VPIP of 8.2% or 34.1%,
they clearly are not playing an optimul number of hands. Examining stats will not
take a 1.5BB/100 winner, and turn him/her into a 2.2BB/100 winner. These improvements
need play time and hand posts.

You might be calling the correct pecentage of river bets, but that doesn't tell us
that you are calling the RIGHT rivers.






Preface:


The two most commonly used statistics when measuring a group of data are: mean
and standard variation.


Mean: This is simply the average. You add all the numbers together, and divide
by the total number of observations.

Standard Deviation: This is the measure of spread. I will leave the complicated
formula out of this. Basically, the further the data tends to fall from the mean, the
greater the standard deviation.

For example:

{5,7,9,11,13} and {1,3,9,15,17}

have the same mean: 9, but the second set has a greater standard deviation.

In addition to these two statistics, the following will also be used:

A one-half standard deviation range about the mean: This is a range that measures

from
0.5 standard deviations below the mean to 0.5 standard deviations above the mean.

For example: In a data set with: mean = 10; standard deviation = 6;

This range is: 7 - 13.


Min: Smallest datum in the set.


Max: Largest datum in the set.





Methodology:


I asked for stat submissions from 2/4 and 3/6 players in the small stakes forum.

I received 21 sets of stats from 2/4 players and 10 from 3/6 players.

(This ended up being roughly 504,000 hands for 2/4 and 313,000 for 3/6).

Using S-Plus software, I proceeded to compute the data in the preface.

Thanks:

I owe many thanks to all those who sent me their stats. As some did it anonymously,
I can't name names here. But you know who you are. Thanks!

this is really cool stuff. I'd participate in any updates.

I steal more, defend my SB less, and win more often when I see the flop than average. I am also looser from the button. interesting stuff...

Well, I'm not surprised to see that I have the highest VPIP and PFR, though someone beats me from the BB.

Thanks this is interesting. I only wish we could corrolate some of these numbers with actual results. Later,

Mike

CallMeIshmael,

Would it be difficult for you to compute baseline SD values for all of the stats you presented? I.E. What is the average SD/100 of a stat like W$SD. Also, what is the standard deviation of the standard deviation of a stat like W$SD. I have always wanted to determine those values for 15/30 full ring and 10/20 6-max, because it would aid PT reads, but I do not have any statistical/database analysis software.
