Odds Mean
Posted : admin On 4/13/2022You’re betting on horse races and want to know how much your winning bet will give you. To compute your $2 win price, take the odds of your horse and multiply the first number by 2, divide that by the second number, and then add $2 — simple as that! Following is a list of.
A certain number of points given beforehand to a weaker side in a contest to equalize the chances of all participants. The ratio of the probability of an event's occurring to the probability of its not occurring. If you bet on sporting events, you must be able to read odds and understand what they mean. Furthermore, you need to quickly calculate the potential winnings for different bets, especially if the. Noun (usually used with a plural verb) the probability that something is so, will occur, or is more likely to occur than something else: The odds are that it will rain today. The ratio of probability that something is so, will occur, or is more likely to occur than something else. Whenever you see a minus-sign, that’s how much you have to bet to win $100. In summary, minus + a number means you BET that amount for every $100 you want to win. Plus + a number means you WIN that amount for every $100 you bet. Hockey Betting Odds: Standard hockey betting operates on the money line. Look at the money line as simply a way to express odds.
Sometimes it is necessary to figure out the average odds from a set of betting odds which can then be used as the basis for further calculations. For example, computing deviation and variance.
When using odds in European format (decimal) you can be forgiven for thinking that average betting odds are simply computed by building the arithmetic mean of the data to be analysed. Unfortunately, this is the wrong approach and leads to a deceptive result.
As a reminder, European odds are calculated as the reciprocal of the statistical probabilities of each event:
and vice versa … The implied probabilities are the reciprocals of the odds:
In effect, European odds are ratios/relations representing the likelihood of an event happening in comparison to each other event (e.g. a bet priced at odds of 4.0 is half as likely to win as a bet with odds of 2.0).
If these ratios are averaged using arithmetic mean (a common error), high data points are given greater weights than low data points. (e.g. working out the arithmetic mean of a set of 20 odds, 19 of them between 2.0 and 2.4, would be skewed if the 20th figure was, say, 15.0).
The correct approach is to calculate average odds by forming the harmonic mean!
The harmonic mean is defined as the reciprocal of the arithmetic mean of the reciprocals of x1, x2, …, xn (the odds):
As the reciprocals of betting odds are the implied probabilities of the events, one can calculate the harmonic mean as a reciprocal of the average probability of the respective bets:
The above equations rearranged facilitates the harmonic mean calculation by dividing n (the number of matches) by the sum of the reciprocals of the odds:
Or alternatively… dividing n (the number of matches) by the sum of their individual probabilities:
The Result (Harmonic Mean) is the Accurate Average of the Betting Odds.
