In descriptive statistics, the interquartile range (IQR), also called the midspread, middle 50%, or H‑spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q3 − Q1. In other words, the IQR is the first quartile subtracted from the third quartile; these quartiles can be clearly seen on a box plot on the data. It is a trimmed estimator, defined as the 25% trimmed range, and is a commonly used robust measure of scale.
In logic and related fields such as mathematics and philosophy, if and only if is a biconditional logical connective between statements, where either both statements are true or both are false.
Q or q is the 17th letter of the modern English alphabet and the ISO basic Latin alphabet. Its name in English is cue, plural cues.
Q is a fictional character as well as the name of a race in Star Trek appearing in the Next Generation, Deep Space Nine, and Voyager series, as well as in related media. The most familiar Q is portrayed by John de Lancie. He is an extra-dimensional being of unknown origin who possesses immeasurable power over time, space, the laws of physics, and reality itself, being capable of altering it to his whim. Despite his vast knowledge and experience spanning untold eons, he is not above practical jokes for his own personal amusement, for a Machiavellian and manipulative purpose, or to prove a point. He is said to be almost omnipotent, and he is continually evasive regarding his true motivations.
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
An electric field surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them. Electric fields are created by electric charges, or by time-varying magnetic fields. Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces of nature.
In mathematics, the quaternions are a number system that extends the complex numbers. They were first described by Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. A feature of quaternions is that multiplication of two quaternions is noncommutative. Hamilton defined a quaternion as the quotient of two directed lines in a three-dimensional space or equivalently as the quotient of two vectors.
The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. It was first stated by Émile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law. The ideal gas law is often written in an empirical form:
Deductive reasoning, also deductive logic, is the process of reasoning from one or more statements (premises) to reach a logically certain conclusion.
The Dead Sea Scrolls are ancient Jewish religious manuscripts found in the Qumran Caves in the Judaean Desert, near Ein Feshkha on the northern shore of the Dead Sea in the West Bank, Palestine. Scholarly consensus dates these scrolls from the last three centuries BCE and the first century CE. The texts have great historical, religious, and linguistic significance because they include the second-oldest known surviving manuscripts of works later included in the Hebrew Bible canon, along with deuterocanonical and extra-biblical manuscripts which preserve evidence of the diversity of religious thought in late Second Temple Judaism. Almost all of the Dead Sea Scrolls are held by the State of Israel in the Shrine of the Book on the grounds of the Israel Museum, but ownership of the scrolls is disputed by Jordan and the Palestinian Authority.
Exclusive or or exclusive disjunction is a logical operation that outputs true only when inputs differ.
Capacitance is the ratio of the change in electric charge of a system, to the corresponding change in its electric potential. There are two closely related notions of capacitance: self capacitance and mutual capacitance. Any object that can be electrically charged exhibits self capacitance. A material with a large self capacitance holds more electric charge at a given voltage than one with low capacitance. The notion of mutual capacitance is particularly important for understanding the operations of the capacitor, one of the three elementary linear electronic components.
Q is a popular music magazine published monthly in the United Kingdom. It was founded in 1986 by the journalists and broadcasters Mark Ellen and David Hepworth, who were presenters of the BBC television music series Whistle Test.
Kamaal Ibn John Fareed, better known by his stage name Q-Tip, is an American rapper, record producer, singer, actor and DJ. Nicknamed The Abstract, he is noted for his innovative jazz-influenced style of hip hop production and his philosophical, esoteric and introspective lyrical themes. He embarked on his music career in the late 1980s, as an MC and main producer of the influential alternative hip hop group A Tribe Called Quest. In the mid-1990s, he co-founded the production team The Ummah, followed by the release of his gold-certified solo debut Amplified in 1999. In the 2000s, he released the Grammy Award-nominated album The Renaissance and the experimental album Kamaal the Abstract.
The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the de Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. Three sizes were offered: initially the 37–40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the 68–90 seats -400 from 1999, still in production. The Q Series are post-1997 variants fitted with active noise control systems.
QAnon is a far-right conspiracy theory detailing a supposed secret plot by an alleged "deep state" against U.S. President Donald Trump and his supporters. The theory began with an October 2017 post on the anonymous imageboard 4chan by someone using the name Q, a presumably American individual, but probably later a group of people, claiming to have access to classified information involving the Trump administration and its opponents in the United States. Q has falsely accused many liberal Hollywood actors, Democratic politicians, and high-ranking officials of engaging in an international child sex trafficking ring, and has claimed that Donald Trump feigned collusion with Russians in order to enlist Robert Mueller to join him in exposing the ring and preventing a coup d'état by Barack Obama, Hillary Clinton, and George Soros. "Q" is a reference to the Q clearance used by the Department of Energy. QAnon believers commonly tag their social media posts with the hashtag #WWG1WGA, signifying the motto "where we go one, we go all."
A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q ; it was thus denoted in 1895 by Giuseppe Peano after quoziente, Italian for "quotient".
Coulomb's law, or Coulomb's inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. The quantity of electrostatic force between stationary charges is always described by Coulomb's law. The law was first published in 1785 by French physicist Charles-Augustin de Coulomb, and was essential to the development of the theory of electromagnetism, maybe even its starting point, because it was now possible to discuss quantity of electric charge in a meaningful way.
