Statistics Terminology ~ The Heuristic Technique

A heuristic is a particular technique of directing one's attention in learning, discovery, or problem-solving. It is originally derived from the Greek "heurisko" (ευρίσκω, the verb from which Archimedes's famous exclamation of "eureka" was derived), which roughly means "I found".

This term was introduced in the 4th century AD by Pappus of Alexandria.

Sunday's Reflexions on Basketball Statistics:
About the Total Team Rebounding Percentage in Basketball Statistics

The total number of rebounds taken per 40 / 48 minutes is a very good way to evaluate rebounders but the game analyst must ever take into account that some players have the opportunity to grab more rebounds than others.

A logical way to evaluate rebounders is by percentage of all missed shots when they are in the game that they rebound. This is usually estimated by another systems through their team's and opponent's rebounds per minute, but the eBA Basketball Analysis System uses the exact numbers throughout the quintets analysis per minute.

This is known as Rebound Rate or Rebound Percentage (Reb%).

Reb% = Reb / (((TmReb + OppReb)/TmMin)*Min)

Photograph: collegian.com

The total team rebounding percentage is the average of its offensive and defensive rebounding percentages.

Team OReb% = TmOReb / (TmOReb + OppDReb)
Team DReb% = TmDReb/ (TmDReb + OppOReb
Team Reb% = (Team OReb% + Team DReb%)/2

When we make the rebounds analysis at the team level, rebound percentage takes into account the fact that good teams usually outrebound their opponents because defensive rebounds are easier to get than offensive rebounds.

At the player level, the rebound percentage analysis are divided into offensive and defensive rebounding, which can prove being a clear perception because few players are equally productive at both.

In a combined analysis at both levels the game analyst must take in account that actually offensive rebounding depends to a considerable degree on whether the coach chooses to crash the boards or play back to prevent fast breaks.

A Scout's-Eye View of the Basketball Game by David Friedman

From 20 Second Timeout
By David Friedman
Download source here: ' A Scout's-Eye View of the Basketball Game ' by David Friedman

"... I recently had the opportunity to spend some time with Indiana Pacers scout Kevin Mackey and learn how a professional basketball talent evaluator watches a game ... "

"... The first thing that a scout must consider is talent: can this player play at the NBA level and contribute in a meaningful way? Physically, a scout is looking for players who have an NBA body and NBA athleticism. Next, a scout evaluates if the player can do these things at the NBA level: (1) shoot; (2) get open; (3) rebound; (4) pass. ..."

"... Mackey says that most players are not equipped to play both ends of the floor and sometimes it is difficult to project how a player’s skills will translate from college to the pros. For instance, will a great college shooter be able to get his shot off in the pros? ..."

"... He says, "Players have DNA" —unique traits that form their identities as athletes. What if a player who is lightly regarded plays extremely well? Then Mackey has to determine if the player just got hot for one game, had a favorable matchup or has in fact improved his skills. He will make a note to follow this player’s performance for the rest of the season. If the player was completely off of the radar, the likelihood is that he just had one good game and will soon revert back to his normal level. ..."

Basketball Statistics Analysis Referred Concepts:
About the Basketball Statistics and the Offensive Rebounding Percentage

In the circumstance that a team does miss a shot, it can prolong its possession and give itself an additional chance to score by rebounding its own misses.

Scoring this points are called "second chance points". We use the following formula for this stat:

Oreb% =
Offensive Rebounds / (Offensive Rebounds + Opponent's Defensive Rebounds)

In this way, we only measure how many rebounds our team catches based on what's obtainable. We use this method instead of another, by example, "team offensive rebounds per game" which will give us "a good offensive rebound team" when a team that shoots 30% and probably catches a lot of offensive rebounds, whether they're a good rebounding team or not.

Photograph: Pete Marovich Images

Applying Oreb%, we're looking at a ratio of how many rebounds our team grabbed compared to how many were accessible.

Rebound rate (RbR)=
(Total Rebs * (Team MP / 5)) / (MP * (Team Total Rebs + Opp Ttotal Rebs)) * 100

Rebound rate is an estimate of the percentage of missed shots a player rebounded while he was on the floor.

Basketball Registering Stats Referred Questions:
About a Travel Violation on a Player Outside the Court

"... Can a travel be called on a player outside the court, clock stopped and the player is given the ball for a pass in? ..."

A travel violation cannot be called, but a throw in violation can be called.
A player taking a throw-in shall not:

 • Take more than five (5) seconds to release the ball.
 • Step into the playing court while having the ball in his hand(s)Cause the ball to touch out-of-bounds, after it has been released on the throw-in.
 • Touch the ball on the playing court before it has touched another player.
 • Cause the ball to enter the basket directly.
 • Move a total distance from the designated throw-in place, laterally in one or in both directions, not to exceed a total of one (1) metre before or while releasing the ball.
He is, however, permitted to move directly backwards from the line as far as circumstances allow.

Photograph: Jeff Blake for The State

eBA Basketball Statistics Registration=
In the case of a throw-in violation:

- if the player take more than five (5) seconds to release the ball, without opponent interference, a 'personal unforced turnover' in the 'throw in' category will be registered;

- when the violation is caused by the opponent action, a team closed defense for example, we'll register a 'team forced turnover' in the 'throw in' category.

Statistics Books Review:

Wages of Wins: Algorithm Explanation
By David Berri, Martin Schmidt, and Stacey Brook

The Wages of Wins: Taking Measure of the Many Myths in Modern Sport, is a book written by three economists —David Berri, Martin Schmidt, and Stacey Brook— who have come up with an algorithm for assessing the value of professional basketball players, using econometric methods to objectively valuate basketball statistics in terms of their impact on winning games. The basic theory of the authors is that measurements of a player's efficiency are better tools for evaluating players than statistics like "points per game." Since teams have an equal number of possessions in a basketball contest, the team that efficiently uses those possessions is more likely to win. Turning the ball over without scoring is "bad," while converting a possession into points is "good." The authors regressed nine statistics to find their relative impact on wins. Here's a simplification of their findings.

"Good" statistics: Each point, rebound, and steal have relatively equal impacts on winning. They are about twice as important as each block and assist. So, to quantify the positive statistics, here's a simple formula: points + rebounds + steals + 1/2 (blocks) + 1/2 (assists)

"Bad" statistics: field goal attempts and turnovers have equally negative impacts on winning. They are twice as bad as free throw attempts and personal fouls. Here's a simple formula for the "bad" stats: field goal attempts + 1/2 (free throw attempts) + turnovers + 1/2 (personal fouls)

Putting this all together we get what the authors call a "Win Score":

Points + Rebounds + Steals + 1/2 (blocks) + 1/2 (assists) - field goal attempts - 1/2 (free throw attempts) - turnovers - 1/2 (personal fouls)

Win Score proves to be an excellent method of comparing players who play the same position. But since power forwards and centers tend to have higher average Win Scores than guards, adjustments need to be made when comparing little men to big men.

Sunday's Reflexions on Basketball Statistics:
About the Fastbreak Points Per 48 Minutes in Basketball Statistics

"... Does the eBA Basketball Statistics Analysis System tracks team fastbreak points game by game and current season average ?

May be the actual basketball game is allowing quick players more access to the lane because of a more rigorous and frequent handchecking calls ?
May be that scoring and FG shots and possessions are down ? ..."

Certainly, the eBA Basketball Statistics Analysis System tracks team fast-break points game by game and current season average. Some numbers about our total season data:

 • Officials are currently calling the games nearer, that means more non-shooting fouls. So, teams are receiving added time per possession ascribable to the shot clock getting reset more frequently.

 • Scoring and Field Goals shots and possessions are going down and average duration of possession in game clock time is raising: therefore putting all together we can conclude that the pace has decelerated a little.

 • Using our possessions formula - see eBA Encyclopedia - and team data from our archives, the average duration of possession reveal us a possession use in a slower pace: moved from 15.83 seconds to 15.88 seconds.

 • And finally, fast-break frequency and points made from stayed the same, personal fouls raises 0.57%, turnovers moves lower 0.6%, steals moves lower 4.6%, blocked shots moves lower 3.4%, assists moves lower 3.2%, total rebounds moves lower 2.2%, shooting percentages are raising but field goal attempts moves lower 0.3% and 3 points attempts raises 1.5%.

The Importance of Efficiency by Jon Nichols

From Basketball-Statistics.com
Download source here: ' The Importance of Efficiency '
by Jon Nichols

"... As I have mentioned before and as you noticed in its description, Composite Score is heavily influenced by how efficient a player is. This is much more noticeable for the offensive aspect of the ratings. Offensive Rating and Player Efficiency Rating are especially influenced by it. ... "

"... What matters is making the most out of every possession and forcing the opposing team to waste their possessions. The Golden State Warriors finished with the most points per game last year, but they were not the best offense in the league (they ranked just 4th) ..."

"... The same general logic holds true when examining individual players. Any time a player takes or shot (or commits a turnover, gets to the foul line, etc.), he is taking away a potential shot from a teammate. Therefore, the best players are the ones that make the most out of the shots they take. It’s a hard concept to grasp for many people, but it’s proven. ..."

"... With that being said, the best players have the right balance between carrying the workload and being efficient. True offensive superstars can run offenses yet still make a high percentage of their shots. The overrated players tend to be the ones that do all those things except for being efficient. ..."

About the Layman’s Guide to Advanced NBA Basketball Statistics

"... This guide is intended for those that are interested in modern basketball statistics. In order to make it more accessible, I’ve decided to forgo the formulas and numbers. At times both fans and journalists alike struggle to use stats when it comes to basketball.

Often enough, their interpretation is inadequate because they don’t have the right stats to explain what is happening on the court. Even worse is when stats are used improperly to arrive at the wrong conclusion. ..."

"... Over the past few years basketball statisticians have learned a lot about the game. While most of it is based on the same stats you would see in boxscores, the findings go far beyond traditional stats. Evaluation on the team level is the most reliable aspect of basketball statistical analysis.

In other words, we’re very sure what factors lead a team to victory. Although statisticians aren’t exactly sure how player stats equates to wins, there are many ways to better evaluate individuals than the classical stats. ..."

"... The biggest hole in statistical analysis is defensive stats. Blocks, rebounds, and steals aren’t enough to tell the whole story on what happens on defense.
Players who excel in this area of the court usually have strong defensive +/- .

However these numbers tend to fluctuate based on the strength of the team. A player that spends a lot of time on the court with strong defensive players will have their defensive +/- inflated. ..." (Mike K. - KnickerBlogger )

Basketball Registering Stats Referred Questions:
About the Statistical Register of a Held Ball

"... Which is the statistical register when a defender forces an offensive player into a held ball ( also known as 'jump ball' ) situation ? ..."

If your team loses possession of the ball as the result of a held ball, a ball turnover must be charged. The turnover is charged to the person who last has possession of the ball.

We have a turnover when your team has the ball, and you lose it to the other team. A turnover can come in the form of a stolen pass, a pass that you throw out of bounds, it can be where they steal the ball away from your dribbler, it can be where you have a player stand in the paint for over three seconds, etc., etc, etc.

Photograph: UNCW Basketball

When the turnover does occurs or when a bad shot is forced during an ON BALL screen situation, that's means there is a direct influence of an opponent action: the eBA Basketball Statistics Analysis System refers to it as a FORCED TURNOVER. When the turnover does occur WITHOUT any opponent influence or interference: a bad pass you YOURSELF throw out of bounds, we call it an UNFORCED TURNOVER.
The value of the turnover, doesn't vary in our metric, being the same for both types, but the eBA System report give to the coach the total quantity and percentages of Forced and Unforced Turnovers by separate, leading so to a deeper analysis of our possessions.

Basketball Statistics Methods & Formulas:
Statistics Terminology ~ The Ratio Scale

This is a type of MEASUREMENT SCALE for which it is meaningful to reason in terms of differences in scores (see INTERVAL SCALE in the eBA Statistics Encyclopedia) and also in terms of ratios of scores.

Such a scale will have a zero point which is meaningful in the sense that it indicates complete absence of the property which the scale measures. The RATIO SCALE may be either unipolar (negative values not meaningful) or bipolar (both positive and negative values meaningful), and either continuous or discrete.

Sunday's Reflexions on Basketball Statistics:
About the Player's Scoring Possessions in Basketball Statistics

A resumed thought with reference to that "not specified percentage" in each field about which we are speaking related to 'player's scoring possessions' formulas: referred to assists I understand they must be counted and credited based on the length of the shots, as done at the eBA System.
Long shots must be credited with a 25% to the player serving the assist, meanwhile short shots, layups or shots within two meters +/- of the basket, in a relative manner easy shots, must be credited with a 50%. Finally medium range shots would have the credit of a 63% for the shooter and only the 37% for the player serving the assist, quantification which may be a proper average for assist in general.

Therefore, the individual floor % is just a player's scoring possessions divided by his total possessions. This statistic take into consideration all areas of a player's offensive contribution, with the possible omission of his offensive rebounds, which are counted not in a forthright manner in the total possession formula.

On many occasions, field goal percentages and free throw percentages are referred as measures of a player's scoring efficiency. For guards, assist to turnover ratios are frequently referred. Individual floor % summarize all this into one number having a purpose. Thoughts ?

Basketball Statistician's Digest:
February 2010 Basketball Statistics Case Study Conclusion

"... A1 shoots a FTA and the shot hits the rim and bounces on it. A2 goes up and dunks the ball while the ball still is on or above the rim ...

And which is the statistical rule in the case A2 converts the basket after the ball has bounced to the side and it is obvious A1’ shot will not be successful.

What is the statistical registration according to the eBA Basketball Statistics Analysis System in each one of the given situations, including the type of the registration ( forced, unforced, neutral, etc...) ... ?"

Photograph from Countdown2Lebron

Conclusion:
eBA System Statistics Fundamentals:
Don't charge a player for a shot from the free-throw line determined by the illegal actions of himself, or any teammates or opponents except when the shot results in a FTM .

Rule Interpretation:
- in the first case, since the free throw does not end until it is certain that the shot will not be successful, the interference was on A1’ shot.
- in the second case, since A1’ shot obviously had missed the game goes on.

eBA Basketball Statistical Registration:
- in the first case, an interference on A1’ shot. Do not charge A1 with a FTA. Do not charge A2 with a FGA . Do not credit A2 with an offensive rebound, but do charge A2 with an UNFORCED turnover.
- in the second case, charge A1 with a FTA missed. Credit A2 with an offensive rebound and a FGM, and charge a FGA.

This Case Study was presented as every 10th. day of each month, on February 10th, 2010 in our eBA Portal: were sent 521 answers, and 34 totally correct, that's means including all the options, registrations and qualifications.

Statistics Terminology ~ The Standard deviation

In probability and statistics, the standard deviation of a probability distribution, random variable, or population or multiset of values is a measure of the spread of its values. It is usually denoted with the letter σ (lower case sigma). It is defined as the square root of the variance.

To understand standard deviation, keep in mind that variance is the average of the squared differences between data points and the mean. Variance is tabulated in units squared. Standard deviation, being the square root of that quantity, therefore measures the spread of data about the mean, measured in the same units as the data.

Said more formally, the standard deviation is the root mean square (RMS) deviation of values from their arithmetic mean.

For example, in the population {4, 8}, the mean is 6 and the deviations from mean are {−2, 2}. Those deviations squared are {4, 4} the average of which (the variance) is 4. Therefore, the standard deviation is 2. In this case 100% of the values in the population are at one standard deviation of the mean.

The standard deviation is the most common measure of statistical dispersion, measuring how widely spread the values in a data set are. If many data points are close to the mean, then the standard deviation is small; if many data points are far from the mean, then the standard deviation is large. If all the data values are equal, then the standard deviation is zero.

For a population, the standard deviation can be estimated by a modified standard deviation (s) of a sample.

Sunday's Reflexions on Basketball Statistics:
About the Plus Minus Ratings in Basketball Statistics

"......With regard to this item: I like the plus-minus statistic - how does the team perform with Player A on the court, compared to how they perform without him - but as some of the other articles you point to probably say, this measure can be problematic.

A major issue is efficiency: there can be a lot of "noise" --- stochastic variability --- in the stat. Fortunately ( from the point of view of a plus-minus statistic ) basketball has a lot of scoring and a long season, so stochastic variability is much less of a problem than in, say, baseball or hockey.

But still, you really want/need to adjust for quality of the other players on the court ( on both teams ). It's also desirable to adjust for the game situation: in a blowout victory or loss, little or nothing is learned from performance in "garbage time," for example.

Of course, some of the same problems come up with any analysis, whether plus-minus or not. No matter how you slice it, you're looking at a non-trivial bit of analysis. That said, I like the plus-minus approach. ......."

The Prouty is a method of rating players created by Jon Scott, based on averaging four areas: Offensive Efficiency, Total Offense, Possessions Gained and Win Rating. The various individual parts are based on a per minute basis.

The Formula: The Prouty Rating is calculated as

[ {Points / (Field Goals Attempted * 2 + FTA) } +
{ (Points + Assists * 2 - Turnovers) / Minutes} +

{ (Rebounds + Steals + (Blocks / 2) - Personal Fouls) / Minutes} +
{ (Minutes / (TEAM TOTAL MINUTES / 5) } * Team Winning Pct} ] / 4

Basketball Registering Stats Referred Questions:
About the Excessive Swinging of the Elbows & Statistics

"... Team is up by 3 with ball control at the end of 4th. quarter, running the clock out waiting for the defensive foul to stop the clock.
Player with the ball, close defender two handed mildly pushed him and the ball-handler, trying to protect the ball, swings his elbows not in an aggressive way but in a defensive way.
The referee blew the whistle and said no foul but it is a
turnover against the ball-handler for "excessive swinging of the elbows".
"Swinging elbows" Turnover is a real rule or an official error ? Forced or Unforced ? Stats Register ? ..."

Rule Statement: "A player shall not excessively swing his/her arms or
elbows even without contacting an opponent." The rules penalty was changed to a violation from a technical foul in order to encourage it's being called more.

Rule Interpretation: Throw-in for the opponents

eBA Statistical Register: Forced ( by the opponent's aggressive defense ) Turnover against the ball-handler and Forced Steal in favour of the close defender.

See in our forum the 'forced turnover' topics and the exposition "Basketball Turnovers Statistical Analysis" at eBA ONLINE.

February 2010 eBA Best Seller:

Hard Work: My Life On and Off the Court
By Roy Williams and Tim Crothers
with foreword by John Grisham

Roy Williams, head coach of the University of North Carolina men’s basketball team, the Tar Heels, has the highest
winning percentage in NCAA history.
Over the last seven years, the 58-year-old Asheville, N.C., native—who was inducted into the Hall of Fame in 2007—has won 205 games, including 24 in the NCAA Tournament.
That’s more Final Fours, more wins, and more NCAA Tournament victories than any basketball coach in the nation.

Hard Work tells the story of Roy Williams’ life that few people know, in Williams’ own distinct and colorful way—his troubled upbringing, his college years, his years of trying to make ends meet before becoming a head coach.

It reveals how determination took him from an impoverished home in the mountains of North Carolina to the very pinnacle of coaching success, culminating in the 2009 NCAA National Championship (his second in five years).
And it pulls back the curtain on one of college basketball’s most guarded programs as witnessed by one of the most successful, dominant coaches, at the prime of his power.
