Basketball Statistics Referred Concepts: Statistics Lies, Uses and Misuses of Statistical Graphs

Basketball Statistics Referred Concepts:
Reflections about Statistics Lies, Uses and Misuses of Statistical Graphics

Basketball Statistics Analysis Referred Concepts
At the last weekly meeting of the concluded eBA Basketball Statistics Tracking Annual Clinic we were discussing the topic of the statistics lies which was initiated by the exposition "Statistics & Statisticians" at eBA ONLINE.

Here is the opinion of Paul H. Kvam and Joel Sokol from their work "Teaching Statistics with Sports Examples":

Statistical lies are most frequently committed in graphical form, where the eyes can be more easily deceived by spurious trends suggested in a picture. A common abuse is manipulating scales on charts and graphs by truncating, censoring or transforming the axis values.

The next figure shows two different charts showing an increase in average attendance at NCAA Women's Soccer games between 1998 and 2003. The first (blue)chart  is the default Microsoft Excel chart; many statistical software packages, in fact, will restrict both axes to a small set of values that contains the data, which helps the reader focus on chart differences more clearly. However, it also removes the scale of difference from the picture, which has potential to mislead readers who pay little attention to the axis labels.

Average Attendance at NCAA

The reader's sense of proportion can be manipulated further with image-based charts, which are standard in sports publications. As an example, the figure below graphs the season wins for the New England Patriots using clip-art in place of vertical bars.

Season Wins for the New England Patriots

Regular season wins for the New England Patriots, 2002-2003

While the height of the football icons corresponds to the information the graph is meant to communicate, the size of the footballs does not; the Patriots improved 56% in wins between 2002 and 2003, but the increase in area of the football icons is over 140%.

Basketball Statistics Questions: Last FT 2 Seconds To Go, 2 Points Ahead...
& Basketball Statistics Video Case Study

Basketball Tracking Stats Referred Questions:
• 2 Seconds To Go, 2 Points Ahead and Last Free Throw

Basketball Registering Stats Referred Questions
...A well known game situation: 2 seconds to go, 2 points ahead and last free throw. The player intentionally misses the free-throw according with the indications from the bench to avoid a complete 2 seconds possession for the opponent. He succeed and they win the game. Can this action be registered in such way that we don't "punish" the shooter's Evaluation Metrics with a -1 because of the missed free
throw ?

What is the Statistics Tracking Rule according to the eBA Basketball Statistics System Book ? ...

eBA Basketball Statistical Tracking=
If you are performing the analysis by means of video, and you are not sure about those "bench indications". you have no alternative and must register the missed free-throw.

The decibel level at Rupp Arena reached epic levels with Nick Calathes at the free throw line with less than a second remaining.

If you were present at this game, and you heard or saw clearly the coach's indications, you may use the "Team Player" option to register the missed throw, registering this action in the "play-by-play" report.

• About a Traveling Turnover, a 8/10 Seconds Backcourt Violation & Pts Scored in the Wrong Basket

Basketball Tracking Stats Referred Questions
"... A1 jumps and shoots, but B1 taps the ball and is still in A1 ones hand. A1 returns with ball that never left his hand.

Is this jump ball, traveling, or a block shoot? B1 just barely tap the ball in the shooters hand.

And what is the statistician rule according to the eBA Basketball Statistics Analysis System ..."

eBA Basketball Statistics Tracking:
If B1 prevents A1 from releasing the ball, it's a held ball, with the statistical record according the alternating possession rule.

If A1 chooses not to release the ball, it's traveling, recording a forced turnover against A1 and a forced steal in favour to B1, the player deflecting, or team player, depending upon the situation.

"... The 8 / 10 seconds time limit rule violation is a PERSONAL or TEAM turnover ? FORCED or
UNFORCED ?
By the way, all the basketball leagues have this rule ? Any difference ? ..."

eBA Basketball Statistics Tracking:
The 8/10 seconds backcourt violation is generally a TEAM TURNOVER, being FORCED or UNFORCED depending upon the opponent's action: if it is as result of an all or half court press defense (FORCED) or a defender's error (UNFORCED).

"... To whom are credited the points scored in the wrong basket ?
To any player ? To the opponent captain ? And what the stats rule ? Turnover ? ..."

Points scored in the wrong basket are never credited to a player, but are credited to the team in a footnote. Points awarded for basket interference or goaltending by the defense are credited to the shooter. When a live ball goes in the basket, the last player who touched the ball causes it to go there ( from the Instructions & Rules Coverage - Scoring 9. ).

Basketball Statistics Questions: Keeping Stats ~ Downward Flight Ball Interference

Basketball Tracking Stats Referred Questions:
Keeping Stats ~ Downward Flight Ball Interference

Basketball Registering Stats Referred Questions
... After a shot for a goal by A1, the ball is in the air when it is touched in its upward flight by B2 ( or A2 ).

In its downward flight to the basket the ball is touched by B3 ( or by A3 ).

Which is the game rule and the statistical register IN EACH CASE according to the eBA Basketball Statistics Creative Analysis ? ...

Rule Fundamental= If, after a field goal attempt, a player touches the ball while it is in its upward flight , all restrictions related to goal tending and interference shall apply.

Game Rule= The contact of B2 ( or A2 ) with the ball in its upward flight is legal and does not change the status of a shot for a goal . However, the subsequent contact with the ball in its downward flight by A3 or B3 is a violation .

eBA Statistical Tracking= In the case of B3, two or three points are awarded to team A, without any record against B3 - this possession ends with the basket. In the case of A3's violation, the ball is awarded to team B for a throw-in, with an 'Unforced Turnover' record against A3.

About the Basketball Possessions Ending in TO & the True Percentage of Team Poss Used
& the Basketball Training Video in our Monday's Reflexions on Basketball Statistics

Reflexions on Basketball Statistics:
15,97% of the Basketball Possessions End in TO

Basketball Statistician's Monday's Reflexions
How we perform the analysis of one team´s turnovers in relation with other team, let say the next opponent at the next game ?

If a team averages 15 turnovers a game, and the next opponent is a team that forces 15 turnovers a game, is it possible to assume that there will be 15 turnovers for that game ?

Or... we must take the league average as the basic unit to analyze this data: if the league average for turnovers is 16.4 that´s means that each team turnover rate is 109,33% compared to the league...

During the eBA Basketball Statistics Tracking Clinics I expressed my opinion that 'exclusive ratings' and 'scientific formulas' employ only a lacking minimum of the significantly important statistics: turnovers per possession and Defensive turnovers per possession; games won and games lost; etc.

But all other information as playoff game vs meaningless garbage time, recent injuries, possible matchup advantages, etc. (see the thread about eBA System Non Standard Statistics ) are disregarded.

Homecourt advantage is usually disregarded too, (see this thread about Home & Road Stats: differences ) meanwhile the Game Analysis & Scouting takes in account every one of this categories, and much more.

You can reach to the answer to your question by a different way: express the team's turnover proclivity in terms of the proportion of possessions that end in turnover - according to the eBA Basketball Statistics Analysis System Archives: around the 15,97% of the possessions end in turnover.

Los Angeles Lakers shooting guard Kobe Bryant (24), against a 1 vs 4 defense !, has his shot blocked by Chicago Bulls small forward Luol Deng (9) in the final seconds of the second half of their NBA basketball game in Los Angeles on December 25, 2011. The Bulls won 88 to 87. In this UPI photograph by Lori Shepler from Dalje.com presented by #eBAStatsGroup #BasketballStatistics Analysis .
Photograph: Dalje.com

About the true percentage of team possessions used:
We know that the 'Usage Rate' is the formula to determine how many possessions a player uses. But which is its significance ?.

If a player keep an account of a high usage of possessions that means he is the one who has the greatest effect of on how well the team performs ?

So if that team is great and he leads the league in 'usage rate' would that make him the best player in the game ?

The team's offense is a measure of how well its high-usage players are shooting: in a good offense, the high-usage player is usually effective; in a bad offense, the high-usage player is usually ineffective.

The eBA Basketball Statistics Analysis System doesn't applies "Usage Rate" because it's not really measures possessions and doesn't really have anything to do with a player's defense.

We apply a stat that really measures usage:the percentage of team possessions used while on the floor.

Surely a player using up to 25-30% of team possessions is going to have a big effect on how well the offense performs, good or bad; by contrast, teams can get the best of low-efficiency, high-usage players and, rarely but possible, however have some decent offense.

Basketball Statistics Questions: Basketball Full Season Per Minute Statistics don't Round

Basketball Tracking Stats Referred Questions:
Basketball Full Season Per Minute Statistics don't Round

Basketball Registering Stats Referred Questions
"... When a player is on the floor for 3 minutes and 31 seconds, the official boxscore enumerate it as 4 minutes.

How the eBA Basketball Statistics System Book tracks the influential impact on the per-minute numbers when multiplied throughout the whole season have those lost 30 seconds ? ..."

First of all, there is an open topic about "Per Minute Statistics" in the Statistics & Statisticians Board where I'll continue the discussion. But after going there, here you have some thoughts about:

One or some short term data analysis will be determined by random chance. We have studied this issue at the eBA Clinics Chats, and reached to the conclusion that the full season stats don't round game by game, so it's a reasonably exact parameter.

The median for Kobe's shots per minute this season is 0.7. (As always, we're factoring in free throw trips.) In fact, when Kobe shoots more 0.7 shots per minute in a game, the Lakers' offense is slightly better than when he shoots less than 0.7 shots per minute.<br />
There's more data to this effect. It's true that in the aggregate the Lakers have performed better offensively when Kobe is not on the floor, by about five points per 100 possessions. But raw on-off data is extremely noisy, as it doesn't at all account for the other nine players on the court or those replacing the players in question. That's why analytic types much prefer adjusted plus-minus. The best current public iteration for that is ESPN's Real Plus-Minus. In that measure, Kobe rates at +1.47 on offense. <br />

It is assumed that throughout a full season there are as many round-downs as round-ups which would take out significant error or bias by amount of time played but there might be a bit of noise in outlying player game logs.

Reflexions on Basetball Statistics: The Basketball Defensive Rebound Efficiency

Reflexions on Basketball Statistics:
Some Reflexions about the Basketball Defensive Rebound Efficiency

basketball 24 Seconds Statistics
"... Talking about turnovers, for example, you might hear someone say, "Our team perpetrated 18 turnovers. That's not very good."

It might not be, but you'd have to know more about the way the game was played to reach that conclusion. 18 turnovers against a slow-down team would be awful. 18 turnovers against  a quick-pace squad would be accomplishable. ..."

"... There's a stat called 'defensive rebound efficiency' that is  used in the eBA Basketball Statistics Creative Analysis System -- it measures the amount of defensive rebounds taken down from missed shots.

Some Reflexions about the Basketball Defensive Rebound Efficiency
Photograph: The LLaBB

There's a similar idea we apply in eBA Basketball Statistics Creative Analysis System as 'offensive rebound efficiency', which simply measures the amount of available offensive rebounds that a team gather.

One area where that stat breaks down, however, is that it's hard to take free throws into account just by looking at the box score because there's no way to know which missed shots could result in an offensive rebound.

This is Kawhi Leonard’s defensive shot chart for the 2013-14 season. Think of it as the inverse of a conventional shot chart: It reflects the shooting behavior of players when Paul was defending them. The sizes of the symbols on the chart correspond to shot frequency; the color of the symbols represents shot efficiency. These defensive shot charts do a good job of showing the relevance of individual defenders. Players like Leonard reduce the effectiveness of whoever they’re guarding.

Basketball Statistics Referred Concepts:
Points per Field Goal Attempt Formula: Concept & Application

Basketball Statistics Referred Concepts:
Points per Field Goal Attempt Formula: Concept & Application

Basketball Statistics Analysis Referred Concepts
In order to measure how strictly correctly a player or team is shooting we need statistics, and if possible a creative analysis of those basketball statistics.

Statisticians most often use the field goal percentage ( FG% ) to do it, but the added bonus of the three-point shot, for instance, isn't reflected in field goal percentage, and the ability to get to the free-throw line (where the points come much easier) is ignored as well.

"Points per Shot Attempt" (PSA): It's a stat designed to reflect the basics of good shooting: getting the greatest number of points from the fewest number of attempts.

this chart provides a useful baseline that we can use to evaluate individual shooting performances. By overlaying players’ shot constellations, we can estimate the expected total number of points that an average NBA shooter would produce, based on where he took his shots; then we can compare a particular player’s actual yield against it.

By overlaying players’ shot constellations, we can estimate the expected total number of points that an average NBA shooter would produce, based on where he took his shots; then we can compare a particular player’s actual yield against it. (Click on the image to continue reading the article!)

Points per shot attempt is simply points divided by shot attempts . Figuring shot attempts is like this: Add field goal attempts plus "Up to the Line" (for 2 or 3 free-throws).

In case of analysis of another team and if you can't know how many times the player or the team reached the line, use (0.4 * FTA) instead.

PSA = Points / (Up to the Line + FGA)

Last years NBA league PSA average was something around 1.039 points per shot attempt, so by averaging, by example, 1.133 points per attempt, an average team gains a full point with every ten shots.

Points per Field Goal Attempt Formula
Photograph: 20 Minutos.es

PSA is just as handy for rating individual players as it is for teams. Occasionally a player will break into the top ten who shoots nothing but dunks, but mostly it's the long shooters who are at the top of an individual PSA list.

This formula, with another fields formulas, are integrated in the 2nd. exposition of the Basketball Statistics Registration eBA Course: "Statistics Formulas Revision", at eBA ANNUAL CLINICS ONLINE.

About the Basketball 'Assist-Turnover Ratio'
& the Basketball Training Video in our Weekly Reflexions on Basketball Statistics

Reflexions on Basketball Statistics:
About the Basketball 'Assist-Turnover Ratio'

Basketball Statistician's Sunday's Reflexions
Reading the 'assist-turnover ratio' from the box-scores, where a player's Ast/TO ratio start to help his team's offensive effectiveness ?

It is clear this level must would be higher for a point guard, but which are the statistical levels ?

Both statistics categories assists and turnovers matter when we note at the European Basketball eBA Archives that 7 of the top 10 AS/TO players are on playoffs teams and of course it does have a positive effect.

 • turnovers are a four factor category according to Dean Oliver's "Basketball on Paper" book;

 • assists suggest good passing and have positive impact on at least 2 of the other three (FG% and FT/FG);

Under the defensive pression of Bryant Mbamalu, freshman guard Denzel Valentine turns the ball over during the game against Louisiana-Lafayette Ragin' Cajuns on Nov. 25, 2012, at Breslin Center. The Spartans beat the Ragin’ Cajuns 60-63. Photograph by Natalie Kolb / The State News

 • TO do not help the offense, but Pts / Reb / Ast do;

 • assists have positive impact on offensive rebounding if the good passes creates a need for help defense;

 • the Basketball Statistics Analysis System separates out 'TO resulting from passes' in our calculations;

 • assists also allow some of the players to focus more on rebounding than looking for their shot;

 • from the eBA Archives top 5 teams on raw assists played the playoffs but 3 of the bottom 5 played too;

 • assists are not one of the four factors categories according to Dean Oliver's "Basketball on Paper" book;

 • as you can see below, the results are different if the PG is also a shooter and/or rebounder - all this things create turnover opportunities-, than if he just brings the ball up and passes;

 • you can play with the following numbers taking into account that this is only a new eBA Research and the break-even points may very well be different for each position:

Forget passing, which player is the best decision maker?3 In this image, Leonard’s shot probability is tied for the most likely outcome, even though by expected possession value it is his worst option; passing to anyone would be better. And these numbers can be tailored to individual players! With substantial sample sizes for individual players over the course of thousands of possessions, we do not have to settle for 'Shooters make X percent of open corner threes', we can specify that 'Player Y makes Z percent of open corner threes'. Which point guard best understands his teammates’ strengths and weaknesses, the differences between the starters and the subs, etc? Which big man has the most added value when getting the ball at the post?  <br />

Work your defender to get him out of position and finish ice-cold with the unblockable running hook shot.

1. Post up Establish contact with the defender in your back. Before you receive the pass make sure that you are in a low and powerful position to keep your balance.

2. Fake baseline Spin to the right to fake out your defender. When he shifts, youve got yourself some space to move.

3. Attack middle Now that you have your defender out of the way, turn round and attack the basket from the centre.

4. Running hook As you approach the basket, use your left arm and shoulder to protect the ball from any block attempts. Then as you take the shot; use your fingertips for extra control and shoot smoothly over your defender into the basket.

About Free Throws Line Up - Rules Differences & Statistics Tracking
& the Basketball Training Video in our Weekly Reflexions on Basketball Statistics

Reflexions on Basketball Statistics:
Free Throws Line Up - Rules Differences & Statistics Tracking

Basketball Statistician's Sunday's Reflexions
At NF - National Federation (U.S. High School):
a- teams are entitled to alternating spots on the lane, with the opponents of the free shooter getting the spots closest to the basket.
b- as many as 8 players can be on the lane (4 each side), and you could have 5 from one team, as any vacant spot can be filled by an opponent.

At NCAA, NBA, FIBA:
a- teams are entitled to alternating spots on the lane, with the opponents of the free shooter getting the spots closest to the basket.
b- only a maximum of 5 players may be on the lane: 3 opponents of the shooter and 2 teammates.

At NBA:
c- the lowest 4 spots MUST be filled on the final throw.

At FIBA:
c- any of the spots may be empty, but must remain empty if the team entitled to them does not fill it.

At NF, NCAA, FIBA:
d- players not in marked lane spots, must remain outside the 3 point arc and behind the free throw line extended until the ball strikes the ring.

At NBA:
d- this part of the rule is somewhat more liberal.

Basketball fans have made an artwork out of distracting the players at free throws time !

Free throws are an organised process, for the statistician too. Let us see something about the basketball statistics tracking in this case. Really, is the shoot we have all the time to record data. The shooter takes his place behind the free throw line (4.5 metres or 15 feet from the basket). All other players must stand in their correct places until the ball leaves the shooter's hands:

The number of players allowed by the rule - according the introduction - lines up along the sides of the restricted area ( keyhole, paint, lane ). These players are normally the ones that rebound the ball. Three or four line up on one side and two or four on the other. In all the rules, a defensive player always takes the place closest to the basket.

The remaining players, must remain behind the three point line and the free throw line extended (an imaginary line extended from the free throw line in both directions to the sidelines).

Leaving their designated places before the ball leaves the shooter's hands, interfering with the ball, and (for the defensive team only) attempting to put off the shooter, are all violations. In addition, the shooter must release the ball within five seconds (ten in the NBA) and must not step on or over the free throw line until the ball touches the ring.

- A violation by the shooter cancels the free throw and the statistician records a missed free throw and a team rebound for the opponents, in case of last free throw;

- a violation by the defensive team results in a substitute free throw if the shooter missed and no stats tracking in the possessions counting, only at the play-by-play relate - see eBA Basketball Statistics Creative Analysis System;

- a violation by the offensive team or a shot that completely misses the ring and backboard results in the loss of possession to the defensive team ( only if it is on the last free throw ), the statistician records a missed last free-throw and a defensive team rebound on FT for the defensive team.

Weekly Reflexions on Basketball Statistics: Who owns the basketball team statistical data?

Weekly Reflexions on Basketball Statistics:
Who owns the basketball team statistical data?

Basketball Statistician's Sunday's Reflexions
When the statistician ends his work and send the game analysis report: is the statistician owed a right to use the data for publication purposes ?

First of all, at the early stages of the season, and in order to eliminate doubt from the beginning of the statistical employment, a document of agreement between the basketball team's manager and the statistician certainly would make clear and more comprehensible each party's respective obligatory preconditions and rights.

If the agreement involves a total permission, we´ll have no any problems.

Now, when the statistician works for a basketball team, data ownership clearly belongs to them.

If it was agreed at the pre-season and contractually that the basketball team owns the data, and the statistician is partially allowed to use the data for publication purposes, obviously there is an obligation to hide the basketball team's and institution's identities to protect their rights to anonymity in accordance with this right of limited use.

In any case, the head coach and the manager should be informed of such intended use of data and supplied with a copy of the final written research.
