Statistics for Dummies
By: Deborah Rumsey
In the numbers explosion all around us in our modern-day dealings, the
buzzword is data, as in, “Do you have any data to support your claim?” “The
data supported the original hypothesis that . . .” and “The data bear this out.
. . .” But the field of statistics is not just about data. Statistics is the entire
process involved in gathering evidence to answer questions about the world, in cases
where that evidence happens to be numerical data.
Statistics For Dummies is for everyone who wants to sort through and evaluate
the incredible amount of statistical information that comes to them on a daily basis. (You
know the stuff: charts, graphs, tables, as well as headlines that talk about the results
of the latest poll, survey, experiment, or other scientific study.) This book arms you
with the ability to decipher and make important decisions about statistical results, being
ever aware of the ways in which people can mislead you with statistics. Get the inside
scoop on number-crunching nuances, plus insight into how you can
- Determine the odds
- Calculate a standard score
- Find the margin of error
- Recognize the impact of polls
- Establish criteria for a good survey
- Make informed decisions about experiments
This down-to-earth reference is chock-full of real examples from real
sources that are relevant to your everyday life: from the latest medical breakthroughs,
crime studies, and population trends to surveys on Internet dating, cell phone use, and
the worst cars of the millennium. Statistics For Dummies departs from traditional
statistics texts, references, supplement books, and study guides in the following ways:
- Practical and intuitive explanations of statistical concepts, ideas, techniques,
formulas, and calculations.
- Clear and concise step-by-step procedures that intuitively explain how to work through
statistics problems.
- Upfront and honest answers to your questions like, “What does this really
mean?” and “When and how I will ever use this?”
Chances are, Statistics For Dummies will be your No. 1 resource
for discovering how numerical data figures into your corner of the universe.

27/08/06 - Basketball plus-minus statistics and multilevel
modeling"..... A cool way to summarize a Basketball player's contribution to
his team is the plus-minus statistic or "Roland rating," which is " the
difference in how the team plays with the player on court versus performance with the
player off court. " (
note: next module at eBA ONLINE - ra )
I had heard of this somewhere and found the details searching on the web, via this page of
Basketball statistics, which led me to Kevin
Pelton's statistical analysis primer, which led me to this page by Dan Rosenbaum
I had been wondering if the plus-minus statistic could be improved by
adjusting for the qualities of the other players and teams on the court, and Rosenbaum has
done just that.
I have a further thought, which is to apply a multilevel model to be able to handle
thinner slices of the data. The issue is that, unless sample sizes are huge, the
adjustments for the abilities of other players and other teams will be noisy. Multilevel
modeling should help smooth out this variation and allow for adjusting for more factors,
or for adjusting for the same factors for shorter time intervals. Sort of like the work of
Val Johnson on adjusting grade point averages for the different abilities of students
taking different courses."

25/08/06 Subject: A Time for Ideas
"For instance, I talked to Dan Rosenbaum a few years ago for some article. We got to
chatting about how old-school stats don't measure so many things that are important. I
trotted out my theory that one of the important ones to track, if you could, would be how
"sticky" a player is. By that I mean, if a ball passes near him anywhere on the
court--a loose ball, a pass, a rebound, a dribbler, anything--what are the chances that
player comes up with the ball?.
Playing Basketball through the years I have noticed that if there's a player on the court
with incredibly sticky hands, his or her team wins more than their fair share of the time.
Not only do they come up with loose balls, steals, rebounds, etc., but just as
importantly, if there's a guy like that on the floor, the offense naturally stays away.
It's a way to own a whole bunch of territory, and force opponents to operate in a limited
space. It's game-changing... . " by Henry Abbott, which complete post may be read

21/08/06: Excerpt of the module edited today at the NEW eBA
110 - Game Stats Register about "Basketball Assists":
...."
"..... the eBA System
refers to "assisted
%" in the following concept: the percentage of the own shots on which an assist was recorded.
In another systems, the eBA Basketball Statistics Analysis System doesn't uses predictions,
you'll find the formulas to predict the assisted field goal percentage employing the "assist share" factor. The assist share is the estimated
percentage of assists a player is responsible for when he's on the floor. This reflects
the fact that the player can't assist to himself..."
" So looking over the effective Assisted % for players - the
percentage of their own shots on which an assist was recorded - we can see players creating its own shot from a top of 90% +/- (generally the
forwards) to an opposite end of a 20% +/- (generally the guards, and specially the point
guard).
One of the keys of this analysis is the three-points specialist rating. The three-point shot are generally assisted and the less often a player shoot, and the more
often this player shoot threes, the more of a three-point specialist the player is, and
his Assisted % would be greater....."

Wilt Chamberlain & Bill Russel - 1972 |
17/08/06 - PGm ( Player Games ). The formula is
Tm G * (( 3 * ( Poss / Tm Poss ) +
3 * ( Stops / Tm Stops ) + ( MP / Tm MP )) / 7 )
Player Games is an estimate of the number of games a
player is responsible for. Poss is an estimate of a player's offensive
possessions and Stops is an estimate of a player's defensive stops. The
formulas for Poss and Stops are quite detailed and can be found in Dean Oliver's Basketball on Paper and at eBA ONLINE

Leading with the Heart 
By Mike Krzyzewski - Coach K
The book has four sections--"Preseason," "Regular Season,"
"Postseason," and "All-Season"--and each of those has four chapters.
Each chapter begins with three quotes ("Too many rules get in the way of
leadership" leads off chapter 1), and ends with bulleted tips summing up the
chapter's message. Between the quotes and the bullet points are anecdotes about Duke
Basketball games and (occasionally) Krzyzewski's life outside Basketball.
What you come away with is an understanding of why Krzyzewski is a great Basketball coach,
why former Duke assistants such as Tommy Amaker and Quin Snyder are probably going to
become great Basketball coaches, and how anyone who's currently a coach can become a
better coach....

13/08/06: James R. Beniger, an associate professor at USC's
Annenberg School of Communications, said it's better to decide which team is the best on
the field -- not through the statistics. "As a statistician, I could find statistics
to prove that USC is the best team in the country, and I could just as easily find some to
show that another team is," said Beniger, who holds a master's degree in statistics
from California. |
10/08/06 - Illegal defense: A rather nebulous
NBA rule that was called irregularly. It's designed to prevent the use of the zone
defense, today legal in the NBA, it was more like a 3-second violation for the defense, in
which no defender can stay in the lane for more than, well, 3 seconds. If you were on
defense and were not aggressively guarding someone, you could not spend more than 3 seconds
in the key at a time.
The term Illegal Defense has replaced Zone
Defense in NBA usage. The rule now in place, supported by guidelines, defines approved
coverage by defensive players and teams. Violations of these rules and guidelines will be
noted as Illegal Defense.
a. Illegal defenses which violate the rules and accepted guidelines set forth are
not permitted in the NBA.
b. When the offensive team is in its backcourt with the ball, no illegal defense
violation may occur
The illegal defense guidelines needed to be eliminated because they
have become problematic. They are problematic for our fans, who don't understand the rule.
They are problematic for the officials, who admittedly have had difficulty administering
the rule. And finally, the teams have used the guidelines in a way that produces isolation
Basketball. Teams identify areas on the floor that they can use to their advantage in a
given offensive matchup and this produces a real sameness of play amongst a lot of the
teams. With isolation Basketball, a lot of NBA teams began standing around. There is
little player movement, there is little ball movement, and there is a decreasing amount of
fastbreak opportunities. These developments began with the misuse of the illegal defense
guidelines and therefore they needed to be eliminated. By eliminating them, the desired
result is to get a game that once again is based on passing, cutting, player movement, and
ball movement. A game that hopefully produces fastbreak opportunities because that is the
way our game should be played.
