From Wikipedia, the free encyclopedia
Cricket is a sport that generates a large number
of statistics.
Statistics are recorded for each player during a match, and
aggregated over a career. At the professional level, statistics for
Test cricket, one-day internationals, and first-class
cricket are recorded separately. However, since Test matches
are a form of first-class cricket, a player's first-class
statistics will include his Test match statistics - but
not vice versa. Nowadays records are also maintained for List A and Twenty20 limited over
matches. These matches are normally limited over games played
domestically at the national level by leading Test nations. Since
one-day internationals are a form of List A limited over matches, a
player's List A statistics will include his ODI match
statistics - but not vice versa.
General
statistics
- Matches (Mat/M): Number of matches played.
(also Played (Pl).)
- Catches (Ct): Number of catches taken.
- Stumpings (St): Number of stumpings made (as a
wicket-keeper).
Batting
statistics
- Innings
(I): The number of innings in which the batsman actually
batted.
- Not
outs (NO): The number of times the batsman was not out
at the conclusion of an innings they batted in.^{1}
- Runs (R): The number of runs
scored.
- Highest Score (HS/Best): The highest score
ever made by the batsman.
- Batting Average (Ave): The
total number of runs divided by the total number of innings in
which the batsman was out. Ave = Runs/[I - NO] (also Avge or
Avg.)
- Centuries (100): The number
of innings in which the batsman scored one hundred runs or
more.
- Half-centuries (50): The number of innings in
which the batsman scored fifty to ninety-nine runs (centuries do
not count as half-centuries as well).
- Balls Faced (BF): The total number of balls
received, including no balls but not including wides.
- Strike
Rate (SR): The number of runs scored per 100 balls
faced. (SR = [100 * Runs]/BF)
^{1} Batsmen who are not required to bat in a particular
innings (due to victory or declaration) are not considered "Not
Out" in that innings. Only the player/s who have taken to the
crease and remained there until the completion of an innings, are
marked "Not Out" on the scorecard. For statistical purposes,
batsmen who retire due to injury or illness are also deemed not out
[1], while batsmen
who retire for any other reason are deemed out [2], except in
exceptional circumstances (in 1983 Gordon Greenidge, not out on 154,
departed a Test match to be with his daughter, who was ill and
subsequently died - he was subsequently deemed not out [3] the only such
decision in the history of Test cricket).
Bowling
statistics
- Overs (O): The number of overs
bowled.
- Balls (B): The number of balls bowled. Overs
is more traditional, but balls is a more useful statistic because
the number of balls per over has varied historically.
- Maiden
Overs (M): The number of maiden overs (overs in which
the bowler conceded zero runs) bowled.
- Runs (R): The number of runs
conceded.
- Wickets
(W): The number of wickets taken.
- Bowling analysis: A shorthand
notation consisting of a bowler's Overs, Maidens, Runs conceded and
Wickets taken (in that order), usually for a single innings but
sometimes for other periods. For example, an analysis of 10-3-27-2
would indicate that the player bowled ten overs, of which three
were maidens, conceded 27 runs and took two wickets.
- No
balls (Nb): The number of no balls bowled.
- Wides (Wd): The number of wides
bowled.
- Bowling Average (Ave): The
average number of runs conceded per wicket. (Ave = Runs/W)
- Economy Rate (Econ): The average number of
runs conceded per over. (Econ = Runs/overs bowled).
- Best Bowling (BB): The bowler's best bowling
performance, defined as firstly the greatest number of wickets,
secondly the fewest runs conceded for that number of wickets.
(Thus, a performance of 7 for 102 is considered better than one of
6 for 19.)
- BBI stands for Best Bowling in Innings and
only gives the score for one innings. (If only the BB rate is given
it's considered the BBI rate.)
- BBM stands for Best Bowling in Match and gives
the combined score over 2 or more innings in one match. (For ODI,
Twenty20 and the like this score is equal to the BBI or BB.)
- Five wickets in an innings (5w): The number of
innings in which the bowler took at least five wickets.
Four wickets in an innings (4w), the number of
innings in which the bowler took exactly four wickets, is
sometimes recorded alongside five wickets, especially in limited
overs cricket.
- Ten wickets in a match (10w): The number of
matches in which the bowler took at least ten wickets; recorded for
Tests and first-class matches only (no bowler has ever taken all
ten wickets in a professional-class limited-overs innings).
- Strike
Rate (SR): The average number of balls bowled per
wicket taken. (SR = Balls/W)
Analysis of cricket
statistics
Although the analysis of statistics has not been performed in a
large-scale "data
mining" manner, professional cricket coaches are beginning to use computer records of
ball-by-ball play to obtain more detailed statistical analysis of
player performances than was previously possible.
Dynamic and graphical
statistics
The advent of saturation television coverage of professional cricket
has provided an impetus to develop new and interesting forms of
presenting statistical data to viewers. Television networks have
thus invented several new ways of presenting statistics.
These include displaying two-dimensional and even
three-dimensional plots of shot directions and distances on an
overhead view of a cricket field, commonly referred to as a
Wagon-Wheel[4]. Other forms
include graphs of run scoring and wicket taking numbers plotted
against time or balls bowled over a career or within a match. These
graphics can be changed dynamically through a computer controlled
back-end, as statistics evolve during a game. Commonly used
graphics, especially during a limited-over match, are a
worm graph[5], called so, for
the worm-like appearance of the teams' score progression as the
overs progress; and; a Manhattan Chart[6], called so, for
its resemblance to the Manhattan skyline.
