A Lifetime Experiment is an experiment instance that measures entity lifetimes.
- Context:
- It can range from being a Single Lifetime Experiment to being a Lifetime Experiment Trial.
- It can report:
- A Start Time.
- A End Time.
- A Lifetime Duration.
- Example(s):
- The fly lived 3.122 days.
- The lightbulb lasted 938.729 hours.
- a Lifetime Hypothesis Testing Experiment.
- a Lifetime Random Experiment.
- …
- Counter-Example(s):
- See: Continuous Experiment Outcome.

- Mean lifetime: If the decaying quantity is the number of discrete elements of a set, it is possible to compute the average length of time for which an element remains in the set. This is called the mean lifetime (or simply the lifetime) and it can be shown that it relates to the decay rate,
- \tau = \frac{1}{\lambda}.
- The mean lifetime (also called the exponential time constant) is thus seen to be a simple "scaling time":
- N(t) = N_0 e^{-t/\tau}. \,
- Thus, it is the time needed for the assembly to be reduced by a factor of e.
