Net Run Rate
Net run rate (NRR) is a statistical method used in analysing teamwork and/or performance in cricket. It is the most commonly used method of ranking teams with equal points in limited overs league competitions, similar to goal difference in football. The NRR in a single game is the average runs per over that team scores, minus the average runs per over that is scored against them. The NRR in a tournament is the average runs per over that a team scores across the whole tournament, minus the average runs per over that is scored against them across the whole tournament. This is the same as the weighted average of the run rates scored in each match (weighted by the lengths of the innings batted compared to the other innings batted), minus the weighted average of the run rates conceded in each match (weighted by the lengths of the innings bowled compared to the other innings bowled). This is ''not'' usually the same as the total or average of the NRRs from the individual matches in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cricket
Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are "out"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match ref ...

Negative Number
In mathematics, a negative number represents an opposite. In the real number system, a negative number is a number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset. If a quantity, such as the charge on an electron, may have either of two opposite senses, then one may choose to distinguish between those senses—perhaps arbitrarily—as ''positive'' and ''negative''. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature. The laws of arithmetic for negative numbers ensure that the common-sense idea of an opposite is reflected in arithmetic. For example, −(−3) = 3 because the opposite of an opposite is the original value. Negative numbers are usually written with a minus sign in front. For example, −3 represents a negative quantity with a magnitude of three, and is pronounced "min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Germany 1–0 Austria (1982 FIFA World Cup)
West or Occident is one of the four cardinal directions or points of the compass. It is the opposite direction from east and is the direction in which the Sun sets on the Earth. Etymology The word "west" is a Germanic word passed into some Romance languages (''ouest'' in French, ''oest'' in Catalan, ''ovest'' in Italian, ''oeste'' in Spanish and Portuguese). As in other languages, the word formation stems from the fact that west is the direction of the setting sun in the evening: 'west' derives from the Indo-European root ''*wes'' reduced from ''*wes-pero'' 'evening, night', cognate with Ancient Greek ἕσπερος hesperos 'evening; evening star; western' and Latin vesper 'evening; west'. Examples of the same formation in other languages include Latin occidens 'west' from occidō 'to go down, to set' and Hebrew מַעֲרָב maarav 'west' from עֶרֶב erev 'evening'.

2013 ICC Champions Trophy
The 2013 ICC Champions Trophy was the seventh ICC Champions Trophy, a One Day International cricket tournament held in England and Wales between 6 and 23 June 2013. India won the competition, beating England by five runs in the final after overcoming South Africa, the West Indies and Pakistan in the group stage, followed by a semi-final victory over Sri Lanka. As winners, India earned $2 million in prize money, the largest amount since the tournament's inception. It was due to be the final ICC Champions Trophy, to be replaced by the ICC World Test Championship in 2017, but in January 2014, it was instead confirmed by the ICC that a Champions Trophy tournament would take place in 2017, with the proposed Test Championship being cancelled. Rules and regulations The 2013 ICC Champions Trophy was contested by eight teams, which were seeded and divided into two groups. Each team played every other team in its group once. Following the group stage, the top two teams from each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duckworth–Lewis–Stern Method
The Duckworth–Lewis–Stern method (DLS) is a mathematical formulation designed to calculate the target score (number of runs needed to win) for the team batting second in a limited overs cricket match interrupted by weather or other circumstances. The method was devised by two English statisticians, Frank Duckworth and Tony Lewis (not to be confused with former cricketer Tony Lewis), and was formerly known as the Duckworth–Lewis method (D/L). It was introduced in 1997, and adopted officially by the ICC in 1999. After the retirements of Duckworth and Lewis, Professor Steven Stern became the custodian of the method and it was renamed to its current title in November 2014. The target score in cricket matches without interruptions is one more than the number of runs scored by the team that batted first. When overs are lost, setting an adjusted target for the team batting second is not as simple as reducing the run target proportionally to the loss in overs, because a team wit ...

1999 Cricket World Cup
The 1999 Cricket World Cup (officially known as ICC Cricket World Cup '99) was the seventh edition of the Cricket World Cup, organised by the International Cricket Council (ICC). It was hosted primarily by England, with Scotland, Ireland, Wales and the Netherlands acting as co-hosts. The tournament was won by Australia, who beat Pakistan by 8 wickets in the final at Lord's Cricket Ground in London. New Zealand and South Africa were the other semi-finalists. The tournament was hosted three years after the previous Cricket World Cup, deviating from the usual four-year gap. Format It featured 12 teams, playing a total of 42 matches. In the group stage, the teams were divided into two groups of six; each team played all the others in their group once. The top three teams from each group advanced to the Super Sixes, a new concept for the 1999 World Cup; each team carried forward the points from the games against the other qualifiers from their group and then played each of the qualif ...

One Day International
A One Day International (ODI) is a form of limited overs cricket, played between two teams with international status, in which each team faces a fixed number of overs, currently 50, with the game lasting up to 9 hours. The Cricket World Cup, generally held every four years, is played in this format. One Day International matches are also called Limited Overs Internationals (LOI), although this generic term may also refer to Twenty20 International matches. They are major matches and considered the highest standard of List A, limited-overs competition. The international one day game is a late-twentieth-century development. The first ODI was played on 5 January 1971 between Australia and England at the Melbourne Cricket Ground. When the first three days of the third Test were washed out officials decided to abandon the match and, instead, play a one-off one day game consisting of 40 eight-ball overs per side. Australia won the game by 5 wickets. ODIs were played in white-co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Additive Inverse
In mathematics, the additive inverse of a number is the number that, when added to , yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive. Zero is the additive inverse of itself. The additive inverse of is denoted by unary minus: (see also below). For example, the additive inverse of 7 is −7, because , and the additive inverse of −0.3 is 0.3, because . Similarly, the additive inverse of is which can be simplified to . The additive inverse of is , because . The additive inverse is defined as its inverse element under the binary operation of addition (see also below), which allows a broad generalization to mathematical objects other than numbers. As for any inverse operation, double additive inverse has no net effect: . Common examples For a number (and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtraction
Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign, . For example, in the adjacent picture, there are peaches—meaning 5 peaches with 2 taken away, resulting in a total of 3 peaches. Therefore, the ''difference'' of 5 and 2 is 3; that is, . While primarily associated with natural numbers in arithmetic, subtraction can also represent removing or decreasing physical and abstract quantities using different kinds of objects including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices. Subtraction follows several important patterns. It is anticommutative, meaning that changing the order changes the sign of the answer. It is also not associative, meaning that when one subtracts more than two numbers, the order in which subtraction is performed matters. Because is the additive identity, subtraction of it does not change a number. Subtrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limited Overs Cricket
Limited overs cricket, also known as one-day cricket or white ball cricket, is a version of the sport of cricket in which a match is generally completed in one day. There are a number of formats, including List A cricket (8-hour games), Twenty20 cricket (3-hour games), and 100-ball cricket (2.5 hours). The name reflects the rule that in the match each team bowls a set maximum number of overs (sets of 6 legal balls), usually between 20 and 50, although shorter and longer forms of limited overs cricket have been played. The concept contrasts with Test and first-class matches, which can take up to five days to complete. One-day cricket is popular with spectators as it can encourage aggressive, risky, entertaining batting, often results in cliffhanger endings, and ensures that a spectator can watch an entire match without committing to five days of continuous attendance. Structure Each team bats only once, and each innings is limited to a set number of overs, usually fift ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
