A probability distribution is an idealized frequency distribution. A frequency distribution describes a specific sampleor dataset. It’s the number of times each possible value of a variable occurs in the dataset. The number of times a value occurs in a sample is determined by its probability of occurrence. … See more A discrete probability distribution is a probability distribution of a categorical or discrete variable. Discrete probability distributions only include the probabilities of values that are … See more A continuous probability distribution is the probability distribution of a continuous variable. A continuous variable can have any value between its lowest and highest values. Therefore, continuous probability distributions include … See more Null distributions are an important tool in hypothesis testing. A null distribution is the probability distribution of a test statistic when the null hypothesis of the test is true. All hypothesis tests … See more You can find the expected value and standard deviation of a probability distribution if you have a formula, sample, or probability table of the distribution. The expected value is another name for the mean of a … See more WebOkay, so now we have the formal definitions out of the way. The first example on this page involved a joint probability mass function that depends on only one parameter, namely \(p\), the proportion of successes. Now, let's take a look at an example that involves a joint probability density function that depends on two parameters.
