Life is a characteristic distinguishing physical entities having biological processes (such as signaling and self-sustaining processes) from those that do not, either because such functions have ceased (death), or because they lack such functions and are classified as inanimate.he chemistry leading to life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the Universe was only 10â17 million years old. Though life is confirmed only on the Earth, many think that extraterrestrial life is not only plausible, but probable or inevitable.
In statistics, the studentized range is the difference between the largest and smallest data in a sample measured in units of sample standard deviations. The studentized range, q, is named for William Sealy Gosset (who wrote under the pseudonym  Student ), and was initially evoked by him (1927).The concept was later presented by a number of actual students, Newman (1939) and Keuls (1952) and John Tukey in some unpublished notes.n statistics, the studentized range is the difference between the largest and smallest data in a sample measured in units of sample standard deviations.
