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concept was later presented by a number of actual students, Newman (1939) and Keuls (1952) and John Tukey in some unpublished notes.n statistics, the studentized range is the difference between the largest and smallest data in a sample measured in units of sample standard deviations.

Interquartile, Semi-Interquartile and Mid-quartile Ranges. In a set of data, the quartiles are the values that divide the data into four equal parts. The median of a set of data separates the set in half.The median of the lower half of a set of data is the lower quartile (LQ) or Q 1.The median of the upper half of a set of data is the upper quartile (UQ) or Q 3. The upper and lower quartiles can be used to find another measure of variation call the interquartile range.The interquartile range or IQR is the range of the middle half of a set of data.nterquartile, Semi-Interquartile and Mid-quartile Ranges.
