Did Not Finish
In racing, did not finish (DNF) denotes a result of a participant who does not finish a given race, either because of a mechanical failure, injury, or involvement in an accident. This may also be used in cases where the competitor has hit the time limit for the race, especially in speedcubing. The term is used in: * Automotive racing such as Formula One; NASCAR; IndyCar; off-road racing, including buggy, trucks, kart, and UTVs, both desert and short-track *Motocross and quad racing, both desert and short-track *Horse racing *Competitive cycling *Competitive track and distance running *Competitive snow skiing and snowboarding *Competitive swimming *Speedcubing Race participants try to avoid receiving a DNF, as some associate it with poor driving. Scholarly research Decathlon competitors Numerous studies have sought to figure out why DNF rates vary greatly, even within the same competitive discipline. For example, in track and field, Edouard found a 22% overall DNF rate among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speedcubing
Speedcubing or speedsolving is a competitive mind sport centered around the rapid solving of various combination puzzles. The most prominent puzzle in this category is the 3×3×3 puzzle, commonly known as the Rubik's Cube. Participants in this sport are called "speedcubers" (or simply "cubers"), who focus specifically on solving these puzzles at high speeds to get low clock times and/or fewest moves. The essential aspect of solving these puzzles typically involves executing a series of predefined algorithms in a particular sequence with eidetic prediction and finger tricks. Competitive speedcubing is predominantly overseen by the World Cube Association (WCA), which officially recognizes 17 distinct speedcubing events. These events encompass a range of puzzles, including N×N×N puzzles of sizes varying from 2×2×2 to 7×7×7, and other puzzle forms such as the Pyraminx, Megaminx, Skewb, Square-1, and Rubik's Clock. Additionally, specialized formats such as 3×3, 4×4, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ejection (sports)
In sports, an ejection (also known as dismissal, sending-off, disqualification, or early shower) is the removal of a participant from a contest due to a violation of the sport's rules. The exact violations that lead to an ejection vary depending upon the sport, but common causes for ejection include unsportsmanlike conduct, violent acts against another participant that are beyond the sport's generally accepted standards for such acts, abuse against officials, violations of the sport's rules that the contest official deems to be egregious, or the use of an illegal substance to better a player's game. Most sports have provisions that allow players to be ejected, and many allow for the ejection of coaches, managers, or other non-playing personnel. In sports that use Penalty card, penalty cards, a red card is often used to signal dismissals. In some sports, another player is permitted to enter the game in place of the player who has been ejected, but in others the team is required to ...

Did Not Pre-qualify
The following is a glossary of terminology used in motorsport, along with explanations of their meanings. 0–9 ;1–2 finish: When two vehicles from the same team finish first and second in a race. Can be extended to 1–2–3 or 1–2–3–4, etc. depending on a combination of racing series and team size. ;107% rule: Often used in Formula One or other racing series, it is a rule where the driver must qualify the car within 107% of the polesitter's time to be allowed to compete. Variations of this may be used to monitor drivers and warn them to reach the required pace or be parked (disqualified). Similarly, the IndyCar Series uses a 105% rule, and NASCAR has a 115% rule, mainly for performance on track, though IndyCar and NASCAR often adjust the threshold for tracks with very abrasive surfaces (such as Atlanta Motor Speedway) where lap times can be considerably faster with less worn tires. ;200 MPH Club: A lifetime "membership" awarded by the SCTA or another sanctionin ...

Winter Olympic Games
The Winter Olympic Games (), also known as the Winter Olympics, is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France. The modern Olympic Games were inspired by the ancient Olympic Games, which were held in Olympia, Greece, from 776 BCE to 394 CE. The Pierre de Coubertin, Baron Pierre de Coubertin of France founded the International Olympic Committee (IOC) 1,500 years later in 1894, leading to the first modern Summer Olympic Games in Athens, Greece in 1896. The IOC is the governing body of the Olympic movement, Olympic Movement, with the Olympic Charter defining its structure and authority. The original five Winter Olympic Sports (consisting of nine disciplines) were Bobsleigh at the 1924 Winter Olympics, bobsleigh, Curling at the 1924 Winter Olympics, curling, Ice hockey at the 1924 Winter Olympics, ice hockey, Nordic skiing at the 1924 ...

Giant Slalom
Giant slalom (GS) is an alpine skiing and alpine snowboarding competitive discipline. It involves racing between sets of poles ("gates") spaced at a greater distance from each other than in Slalom skiing, slalom but less than in Super-G. Giant slalom and slalom make up the technical events in alpine ski racing. This category separates them from the speed events of Super-G and Downhill (ski competition), downhill. The technical events are normally composed of two runs, held on different courses on the same ski run. Course The vertical drop for a GS course must be for men, and for women. The number of gates in this event is 56–70 for men and 46–58 for women. The number of direction changes in a GS course equals 11–15% of the vertical drop of the course in metres, 13–18% for children. As an example, a course with a vertical drop of would have 33–45 direction changes for an adult race. Speed Although giant slalom is not the fastest event in skiing, on average a well-t ...

Slalom Skiing
Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super-G, super giant slalom and Downhill (ski competition), downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the FIS Alpine World Ski Championships, and at the Olympic Winter Games. History The term slalom comes from the Morgedal/Seljord dialect of the Norwegian language, Norwegian word "slalåm": "sla", meaning "slightly inclining hillside", and "låm", meaning "track after skis". The inventors of modern skiing classified their trails according to their difficulty: *''Slalåm'' was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs. *''Ufsilåm'' was a trail with one obstacle (''ufse'') like a jump, a fence, a difficult turn, a gorge, a cliff (often more than high), et cetera. *''Uvyrdslåm'' was a trail with sever ...

Super-G
Super giant slalom, or super-G, is a racing discipline of alpine skiing. Along with the faster downhill, it is regarded as a "speed" event, in contrast to the technical events giant slalom and slalom. It debuted as an official World Cup event during the 1983 season and was added to the official schedule of the World Championships in 1987 and the Winter Olympics in 1988. Much like downhill, a super-G course consists of widely set gates that racers must pass through. The course is set so that skiers must turn more than in downhill, though the speeds are still much higher than in giant slalom (hence the name). Each athlete only has one run to clock the best time. In the Olympics, super-G courses are usually set on the same slopes as the downhill, but with a lower starting point. History Super-G was run as a World Cup test event during the 1982 season, with two men's races and a women's race that did not count in the season standings. Approved by the International Ski Federa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downhill (ski Competition)
Downhill is a form of alpine skiing competition. Whereas the other alpine skiing events (Slalom skiing, slalom, giant slalom, Super-G, super giant slalom, and alpine skiing combined, combined) emphasize turning and technique, downhill emphasizes "the six components of technique, courage, speed, risk, physical condition and judgement", according to the International Ski Federation, FIS "International Ski Competition Rules (ICR)".. Speeds of up to are common in international competition. Athletes must have an aerodynamically efficient tuck position to minimize drag coefficient, drag and increase speed. The term, "downhill skiing", is also used as a synonym for alpine skiing as a recreational activity. History The rules for downhill skiing competitions were originally developed by Sir Arnold Lunn for the 1925 British National Ski Championships. A speed of was first achieved by Johan Clarey at the 2013 Alpine Skiing World Cup, 2013 Lauberhorn ski races, Lauberhorn FIS Alpine Sk ...

Statistical Significance
In statistical hypothesis testing, a result has statistical significance when a result at least as "extreme" would be very infrequent if the null hypothesis were true. More precisely, a study's defined significance level, denoted by \alpha, is the probability of the study rejecting the null hypothesis, given that the null hypothesis is true; and the p-value, ''p''-value of a result, ''p'', is the probability of obtaining a result at least as extreme, given that the null hypothesis is true. The result is said to be ''statistically significant'', by the standards of the study, when p \le \alpha. The significance level for a study is chosen before data collection, and is typically set to 5% or much lower—depending on the field of study. In any experiment or Observational study, observation that involves drawing a Sampling (statistics), sample from a Statistical population, population, there is always the possibility that an observed effect would have occurred due to sampling error al ...
