In probability theory and statistics, the Weibull distribution / ˈ w aɪ b ʊ l / is a continuous probability distribution. It models a broad range of random variables, largely in the nature of a time to failure or time between events. Examples are maximum one-day rainfalls and the time a user spends on a web page.

It is particularly applicable for modeling failure data measured in discrete units like cycles or shocks.

Remember that guidelines are not set in stone — rather, they're good rules to follow. For instance, if you’re 30 years old and earn $75,000, you should try to have that much saved in your 401(k).
If X is an exponential random variable with mean β, then X 1/γ is a Weibull (γ, β) random variable. The square of a standard normal random variable has a chi-squared distribution with one degree of freedom. If X is a Student’s t random variable with ν degree of freedom, then X 2 is an F (1,ν) random variable.
