Boxplot (with an interquartile range) and a probability density function (pdf) of a Normal N(0,σ 2) Population. In descriptive statistics, the interquartile range (IQR) is a measure of statistical dispersion, which is the spread of the data. [1]
The distribution was first derived by Maxwell in 1860 on heuristic grounds. [5] [6] Boltzmann later, in the 1870s, carried out significant investigations into the physical origins of this distribution. The distribution can be derived on the ground that it maximizes the entropy of the system. A list of derivations are:
Sturges's rule [10] is derived from a binomial distribution and implicitly assumes an approximately normal distribution. k = ⌈ log 2 n ⌉ + 1 , {\displaystyle k=\lceil \log _{2}n\rceil +1,\,} Sturges's formula implicitly bases bin sizes on the range of the data, and can perform poorly if n < 30 , because the number of bins will be small ...
The age distribution based on the 2011 census was as follows. [17] Age group Population % of total 0–4 293,000 5.53 5–9 270,000 5.10 10–14 292,000 5.51
[This] report acknowledges this by adopting a measure that accounts for the economic value of produce." [ 12 ] : 10 Hall et al. (2009) calculated food waste in the United States in terms of energy value "by comparing the US food supply data with the calculated food consumed by the US population."
High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).

Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
