The technique is however equally applicable to discrete distributions. Furthermore, a key challenge in assessing impact is the presence of substantial data gaps, particularly in long time-series.

Bayesian vs. Frequentist Statistics[ edit ] Resampling vs. Bayesian Computation[ edit ] Typically, the question one attempts to answer using statistics is that there is a relationship between two variables. To demonstrate that there is a relationship the experimenter must show that when one variable changes the second variable changes and that the amount of change is more than would be likely from mere chance alone. There are two ways to figure the probability of an event. The first is to do a mathematical calculation to determine how often the event can happen.
The second is to observe how often the event happens by counting the number of times the event could happen and also counting the number of times the event actually does happen.
The use of a mathematical calculation is when a person can say that the chance of the event rolling a one on a six sided die is one in six. The probability is figured by figuring the number of ways the event can happen and divide that number by the total number of possible outcomes. Another example is in a well shuffled deck of cards, what is the probability of the event of drawing a three. The answer is four in fifty two since there are four cards numbered three and there are a total of fifty two cards in a deck.
The chance of the event of drawing a card in the suite of diamonds is thirteen in fifty two there are thirteen cards of each of the four suites. The chance the event of drawing the three of diamonds is one in fifty two. Sometimes, the size of the total event space, the number of different possible events, is not known. For instance, a warranty for a coffee maker is a probability statement. The manufacturer calculates that the probability the coffee maker will stop working before the warranty period ends is low.
The way such a warranty is calculated involves testing the coffee maker to calculate how long the typical coffee maker continues to function. Then the manufacturer uses this calculation to specify a warranty period for the device. Experiments, Outcomes and Events[ edit ] The easiest way to think of probability is in terms of experiments and their potential outcomes.
Many examples can be drawn from everyday experience: On the drive home from work, you can encounter a flat tire, or have an uneventful drive; the outcome of an election can include either a win by candidate A, B, or C, or a runoff.
