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concept was later presented by a number of actual students, Newman (1939) and Keuls (1952) and John Tukey in some unpublished notes.n statistics, the studentized range is the difference between the largest and smallest data in a sample measured in units of sample standard deviations. The studentized range, q, is named for William Sealy Gosset (who wrote under the pseudonym  Student ), and was initially evoked by him (1927).
Then the following random variable has a Studentized range distribution. This distribution is related to the t distribution and is very useful especially in follow up testing for ANOVA such as Tukeyâs HSD (see Unplanned Comparisons).Tables of critical values for this distribution can be found in Studentized Range q Table.Real Statistics Functions: The following functions are supplied by the Real Statistics Resource Pack. QDIST (q, k, df) = value at q of the studentized range distribution with k independent variables and df degrees of freedom.his distribution is related to the t distribution and is very useful especially in follow up testing for ANOVA such as Tukeyâs HSD (see Unplanned Comparisons). Tables of critical values for this distribution can be found in Studentized Range q Table.
