Exponential Distribution describes the times in between events a process in which events occur continuously and independently at a constant average rate.
If the number of occurrences of some event follows a Poisson distribution, the time between successive occurrences will follow an Exponential Distribution.
Characteristics of an Exponential Distribution.
When is the exponential distribution used?
- Describes the times in between events a process in which events occur continuously and independently at a constant average rate.
- To describe the time between successive occurrences when all occurrences follow an Exponential Distribution.
- To predict the length of time that properly maintained equipment will operate.
- To approximate the time between outcomes. (See Poisson)
- When a probability of an outcome is consistent throughout the time period.
