*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.
