Distributions

For the concept of distribution in syllogistic logic, see Distribution of Terms.

In the field of statistics, distributions are functions that represent how sample data are distributed. You may see frequency distributions, which represent the frequency of every value in the distribution, and probability distributions, which represent the probability of an observation being a certain value or within a certain range of values.

One important probability distribution is the normal distribution. There are many others as well.
