# Statistical distribution

A statistical distribution, or probability distribution, describes how values are distributed for a field. In other words, the statistical distribution shows which values are common and uncommon.

There are many kinds of statistical distributions, including the bell-shaped normal distribution. We use a statistical distribution to determine how likely a particular value is. For example, if we have a chi-square value, we can use the chi-square distribution to determine how likely this chi-square value is.
