Starting Prices
In horse racing, the starting price (SP) is the odds prevailing on a particular horse in the on-course fixed-odds betting market at the time a race begins. The method by which SPs are set for each runner varies in different countries but is generally by consensus of an appointed panel on the basis of their observations of the fluctuation in prices at the racetrack. This is done as follows: For each horse the odds offered by the bookmakers are ordered into a list from longest to shortest. This list is then divided into halves and the SP is the shortest odds available in the half containing the longest odds. Thus the SP or a longer price will have been offered by at least half the bookmakers in the sample. ''Note'': This method is slightly different from the method of calculating the median. The principal function of a starting price is to determine returns on those winning bets where fixed odds have not been taken at the time the bet was struck. Typically, on the day of ...

Horse Racing
Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance is in the gambling associated with ...

Odds
Odds provide a measure of the likelihood of a particular outcome. They are calculated as the ratio of the number of events that produce that outcome to the number that do not. Odds are commonly used in gambling and statistics. Odds also have a simple relation with probability: the odds of an outcome are the ratio of the probability that the outcome occurs to the probability that the outcome does not occur. In mathematical terms, where p is the probability of the outcome: :\text = \frac where 1-p is the probability that the outcome does not occur. Odds can be demonstrated by examining rolling a six-sided die. The odds of rolling a 6 is 1:5. This is because there is 1 event (rolling a 6) that produces the specified outcome of "rolling a 6", and 5 events that do not (rolling a 1,2,3,4 or 5). The odds of rolling either a 5 or 6 is 2:4. This is because there are 2 events (rolling a 5 or 6) that produce the specified outcome of "rolling either a 5 or 6", and 4 events that do n ...

Fixed-odds Betting
Fixed-odds betting is a form of wagering against odds offered by a bookmaker or an individual or on a bet exchange. It involves betting on an event in which there is no fluctuation on the payout. In Australia, the practice is usually known as "SP betting". Calculating fixed odds It is customary with fixed-odds gambling to know the odds at the time of the placement of the wager (the "live price"), but the category also includes wagers whose price is determined only when the race or game starts (the " starting prices"). It is ideal for bookmakers to price/mark up a book such that the net outcome will always be in their favour: the sum of the probabilities quoted for all possible outcomes will be in excess of 100%. The excess over 100% (or overround) represents profit to the bookmaker in the event of a balanced/even book. In the more usual case of an imbalanced book, the bookmaker may have to pay out more winnings than what is staked or may earn more than mathematically expected. An ...

Median
In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic feature of the median in describing data compared to the mean (often simply described as the "average") is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of a "typical" value. Median income, for example, may be a better way to suggest what a "typical" income is, because income distribution can be very skewed. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median is not an arbitrarily large or small result. Finite data set of numbers The median of a finite list of numbers is the "middle" number, when those numbers are list ...

Bookmaker
A bookmaker, bookie, or turf accountant is an organization or a person that accepts and pays off bets on sporting and other events at agreed-upon odds. History The first bookmaker, Ogden, stood at Newmarket in 1795. Range of events Bookmakers in many countries focus on accepting bets on professional sports, especially horse racing and association football or Indian Premier League cricket. However, a wider range of bets, including on political elections, awards ceremonies such as the Oscars, and novelty bets are accepted by bookmakers in some countries. Operational procedures By "adjusting the odds" in their favour (paying out amounts using odds that are less than what they determined to be the true odds) or by having a point spread, bookmakers aim to guarantee a profit by achieving a 'balanced book', either by getting an equal number of bets for each possible outcome or (when they are offering odds) by getting the amounts wagered on each outcome to reflect the odds.

Ante-post
In horse racing and greyhound racing, an ante-post bet is a bet placed before the horse/greyhound racing course's betting market has opened, and is made on the expectation that the price of the horse/greyhound is presently more favorable than it will be when the course's market opens. Generally, this includes any bet placed before the day of the race. Ante-post betting, unlike starting price In horse racing, the starting price (SP) is the odds prevailing on a particular horse in the on-course fixed-odds betting market at the time a race begins. The method by which SPs are set for each runner varies in different countries but is genera ... betting, carries the additional risk that the original bet will be forfeited, rather than returned, if the wagered horse fails to run.Hammond (1992), p. 19. The ''ante'' in ante-post is derived from the Latin ''ante'' (meaning "before"), but the ''post'' is not the Latin ''post'' (meaning "after"). Instead, it is derived from the nineteenth centu ...
