However, there are instances in which a complete tabulation is not available. In some of these instances, probability models or mathematical equations can be used to generate probabilities. There are many probability models, and the model appropriate for a specific application depends on the specific attributes of the application. There are two particularly useful probability models: the binomial distribution model, which is useful for computing probabilities about a discrete variable the normal distribution model, which is useful for computing probabilities about a continuous variable. These probability models are extremely important in statistical inference, and we will discuss these next. The Binomial Distribution: A Probability Model for a Discrete Outcome The binomial distribution model is an important probability model that is used when there are two possible outcomes hence "binomial". In a situation in which there were more than two distinct outcomes, a multinomial probability model might be appropriate, but here we focus on the situation in which the outcome is dichotomous.

For example, adults with allergies might report relief with medication or not, children with a bacterial infection might respond to antibiotic therapy or not, adults who suffer a myocardial infarction might survive the heart attack or not, a medical device such as a coronary stent might be successfully implanted or not. These are just a few examples of applications or processes in which the outcome of interest has two possible values i. The two outcomes are often labeled "success" and "failure" with success indicating the presence of the outcome of interest.

Note, however, that for many medical and public health questions the outcome or event of interest is the occurrence of disease, which is obviously not really a success. Nevertheless, this terminology is typically used when discussing the binomial distribution model. As a result, whenever using the binomial distribution, we must clearly specify which outcome is the "success" and which is the "failure". The binomial distribution model allows us to compute the probability of observing a specified number of "successes" when the process is repeated a specific number of times e. We must first introduce some notation which is necessary for the binomial distribution model. First, we let "n" denote the number of observations or the number of times the process is repeated, and "x" denotes the number of "successes" or events of interest occurring during "n" observations. The probability of "success" or occurrence of the outcome of interest is indicated by "p".

The binomial equation also uses factorials. In mathematics, the factorial of a non-negative integer k is denoted by k! For example, 4! There is one special case, 0! With this notation in mind, the binomial distribution model is defined as: The Binomial Distribution Model Use of the binomial distribution requires three assumptions: Each replication of the process results in one of two possible outcomes success or failure , The probability of success is the same for each replication, and The replications are independent, meaning here that a success in one patient does not influence the probability of success in another.

For a more intuitive explanation of the binomial distribution, you might want to watch the following video from KhanAcademy. Examples of Use of the Binomial Model 1. If the medication is given to 10 new patients with allergies, what is the probability that it is effective in exactly seven? First, do we satisfy the three assumptions of the binomial distribution model? The outcome is relief from symptoms yes or no , and here we will call a reported relief from symptoms a 'success. The final assumption is that the replications are independent, and it is reasonable to assume that this is true. What is the probability that none report relief? What is the most likely number of patients who will report relief out of 10? What is the probability that exactly 8 of 10 report relief?

We can use the same method that was used above to demonstrate that there is a The probability that exactly 8 report relief will be the highest probability of all possible outcomes 0 through The Probability of Dying after a Heart Attack The likelihood that a patient with a heart attack dies of the attack is 0. Suppose we have 5 patients who suffer a heart attack, what is the probability that all will survive? We again need to assess the assumptions. It should be noted that the assumption that the probability of success applies to all patients must be evaluated carefully. The probability that a patient dies from a heart attack depends on many factors including age, the severity of the attack, and other comorbid conditions.

Here we want to compute P 2 or more successes. The possible outcomes are 0, 1, 2, 3, 4 or 5, and the sum of the probabilities of each of these outcomes is 1 i. There is a 1. What would be the probability of getting exactly 4 heasds? There are several noteworthy characteristics of this graph. It is bell-shaped with a single peak in the center, and it is symmetrical. If the distribution is perfectly symmetrical with a single peak in the center, then the mean value, the mode, and the median will be all be the same. Many variables have similar characteristics, which are characteristic of so-called normal or Gaussian distributions.

Note that the horizontal or X-axis displays the scale of the characteristic being analyzed in this case weight , while the height of the curve reflects the probability of observing each value. The fact that the curve is highest in the middle suggests that the middle values have higher probability or are more likely to occur, and the curve tails off above and below the middle suggesting that values at either extreme are much less likely to occur.

There are different probability models for continuous outcomes, and the appropriate model depends on the distribution of the outcome of interest. The normal probability model applies when the distribution of the continuous outcome conforms reasonably well to a normal or Gaussian distribution, which resembles a bell shaped curve. Note normal probability model can be used even if the distribution of the continuous outcome is not perfectly symmetrical; it just has to be reasonably close to a normal or Gaussian distribution. Skewed Distributions However, other distributions do not follow the symmetrical patterns shown above.

The standard deviation gives us a measure of how spread out the observations are. It is possible to have BMI values below 11 or above 47, but extreme values occur very infrequently. To compute probabilities from normal distributions, we will compute areas under the curve. For any probability distribution, the total area under the curve is 1.

Answer It is easy to figure out the probabilities for values that are increments of the standard deviation above or below the mean, but what if the value isn't an exact multiple of the standard deviation? For example, suppose we want to compute the probability that a randomly selected male has a BMI less than 30 which is the threshold for classifying someone as obese.

Because 30 is neither the mean nor a multiple of standard deviations above or below the mean, we cannot simply use the probabilities known to be associated with 1, 2, or 3 standard deviations from the mean. In a sense, we need to know how far a given value is from the mean and the probability of having values less than this. And, of course, we would want to have a way of figuring this out not only for BMI values in a population of males with a mean of 29 and a standard deviation of 6, but for any normally distributed variable. So, what we need is a standardized way of evaluating any normally distributed data so that we can compute the probability of observing the results obtained from samples that we take. We can do all of this fairly easily by using a "standard normal distribution. What is the probability that a randomly selected male from this population would have a BMI less than 30?

For example, when rolling a number cube times, predict that a 3 or 6 would be rolled roughly times, but probably not exactly times. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. A — Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. For example, if a student is selected at random from a class, find the probability that Jane will be selected and the probability that a girl will be selected. B — Develop a probability model which may not be uniform by observing frequencies in data generated from a chance process. For example, find the approximate probability that a spinning penny will land heads up or that a tossed paper cup will land open-end down.
