Will Rogers Phenomenon
The Will Rogers phenomenon, also rarely called the Okie paradox, is when moving an observation from one group to another increases the average of both groups. It is named after a joke attributed to the comedian Will Rogers about Dust Bowl migration during the Great Depression: The joke's premise is that Okies (Dust Bowl migrants from Oklahoma) were not as bright as the average Oklahoman, but smarter than the average Californian. This quotation was first attributed to native Oklahoman Rogers decades after his death; versions of the same joke with different places and people circulated at least 15 years before it can be linked to Okies. The apparent paradox comes from the rise in intelligence of both groups, which makes it seem as though intelligence has been "created." However, the overall population maintains the same average intelligence: moving a person of moderate intelligence out of a high-intelligence group and into a low-intelligence group increases the mean intelligence ...

Eponymous Paradoxes
An eponym is a noun after which or for which someone or something is, or is believed to be, named. Adjectives derived from the word ''eponym'' include ''eponymous'' and ''eponymic''. Eponyms are commonly used for time periods, places, innovations, biological nomenclature, astronomical objects, works of art and media, and tribal names. Various orthographic conventions are used for eponyms. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. ''Eponym'' may refer to a person or, less commonly, a place or thing for which someone or something is, or is believed to be, named. ''Eponym'' may also refer to someone or something named after, or believed to be named after, a person or, less commonly, a place or thing. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era, but the Elizabethan e ...

Rob Muldoon
Sir Robert David Muldoon (; 25 September 19215 August 1992) was a New Zealand politician who served as the 31st prime minister of New Zealand, from 1975 to 1984, while leader of the National Party. Departing from National Party convention, Muldoon was a right-wing populist and economic nationalist, with a distinctive public persona described as reactionary, aggressive, and abrasive. After a troubled childhood, Muldoon served as a corporal and sergeant in the army in the Second World War. After a career as a cost accountant, he was elected to the House of Representatives at the 1960 general election as the Member of Parliament (MP) for Tamaki, representing the National Party. Muldoon rose in the Second National Government to serve successively as Minister of Tourism (1967), Minister of Finance (1967–1972), and Deputy Prime Minister (1972). Over this time he built up an informal but solid backing amongst National's mostly rural right faction, which he called "Rob's Mob". ...

Gerrymandering
Gerrymandering, ( , originally ) defined in the contexts of Representative democracy, representative electoral systems, is the political manipulation of Boundary delimitation, electoral district boundaries to advantage a Political party, party, group, or socioeconomic class within the constituency. The manipulation may involve "cracking" (diluting the voting power of the opposing party's supporters across many districts) or "packing" (concentrating the opposing party's voting power in one district to reduce their voting power in other districts). Gerrymandering can also be used to protect incumbents. Wayne Dawkins, a professor at Morgan State University, describes it as politicians picking their voters instead of voters picking their politicians. The term ''gerrymandering'' is a portmanteau of a salamander and Elbridge Gerry, Vice President of the United States at the time of his death, who, as governor of Massachusetts in 1812, signed a bill that created a partisan distri ...

Simpson's Paradox
Simpson's paradox is a phenomenon in probability and statistics in which a trend appears in several groups of data but disappears or reverses when the groups are combined. This result is often encountered in social-science and medical-science statistics, and is particularly problematic when frequency data are unduly given causal interpretations. Judea Pearl. ''Causality: Models, Reasoning, and Inference'', Cambridge University Press (2000, 2nd edition 2009). . The paradox can be resolved when confounding variables and causal relations are appropriately addressed in the statistical modeling (e.g., through cluster analysis). Simpson's paradox has been used to illustrate the kind of misleading results that the misuse of statistics can generate. Edward H. Simpson first described this phenomenon in a technical paper in 1951; the statisticians Karl Pearson (in 1899) and Udny Yule (in 1903) had mentioned similar effects earlier. The name ''Simpson's paradox'' was introduced by Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alvan Feinstein
Alvan Feinstein (December 4, 1925 – October 25, 2001) was an American clinician, health informatician, and epidemiologist who had a significant impact on clinical investigation, especially in the field of clinical epidemiology that he helped define. He is regarded as one of the fathers of modern clinical epidemiology. Education and career Feinstein was born in Philadelphia, Feinstein received his bachelor's degree (BSc 1947) and master's degree (MSc, 1948) in mathematics at the University of Chicago. Feinstein received his medical degree (MD, 1952) at the University of Chicago School of Medicine. He completed his residency training in Internal Medicine at Rockefeller Institute. He was Board Certified in Internal Medicine in 1955 and became the medical director of Irvington House Institute). While there, he studied patients with rheumatic fever and challenged the belief that proper treatment after an early diagnosis kept those patients from developing severe heart disease la ...

Utilitarian
In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that lead to the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea that underpins them all is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described ''utility'' as the capacity of actions or objects to produce benefits, such as pleasure, happiness, and good, or to prevent harm, such as pain and unhappiness, to those affected. Utilitarianism is a version of consequentialism, which states that the consequences of any action are the only standard of right and wrong. Unlike other forms of consequentialism, such as egoism and altruism, egalitarian utilita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subpopulation
In statistics, a population is a set of similar items or events which is of interest for some question or experiment. A statistical population can be a group of existing objects (e.g. the set of all stars within the Milky Way galaxy) or a hypothetical and potentially infinite group of objects conceived as a generalization from experience (e.g. the set of all possible hands in a game of poker). A population with finitely many values N in the support of the population distribution is a finite population with population size N. A population with infinitely many values in the support is called infinite population. A common aim of statistical analysis is to produce information about some chosen population. In statistical inference, a subset of the population (a statistical '' sample'') is chosen to represent the population in a statistical analysis. Moreover, the statistical sample must be unbiased and accurately model the population. The ratio of the size of this statistical sa ...

Average
In colloquial, ordinary language, an average is a single number or value that best represents a set of data. The type of average taken as most typically representative of a list of numbers is the arithmetic mean the sum of the numbers divided by how many numbers are in the list. For example, the mean or average of the numbers 2, 3, 4, 7, and 9 (summing to 25) is 5. Depending on the context, the most representative statistics, statistic to be taken as the average might be another measure of central tendency, such as the mid-range, median, Mode (statistics), mode or geometric mean. For example, the average income, personal income is often given as the median the number below which are 50% of personal incomes and above which are 50% of personal incomes because the mean would be higher by including personal incomes from a few billionaires. General properties If all numbers in a list are the same number, then their average is also equal to this number. This property is shared by each o ...

Orders Of Magnitude
In a ratio scale based on powers of ten, the order of magnitude is a measure of the nearness of two figures. Two numbers are "within an order of magnitude" of each other if their ratio is between 1/10 and 10. In other words, the two numbers are within about a factor of 10 of each other. For example, 1 and 1.02 are within an order of magnitude. So are 1 and 2, 1 and 9, or 1 and 0.2. However, 1 and 15 are not within an order of magnitude, since their ratio is 15/1 = 15 > 10. The reciprocal ratio, 1/15, is less than 0.1, so the same result is obtained. Difference (mathematics), Differences in order of magnitude can be measured on a base-10 logarithmic scale in "Decade (log scale), decades" (i.e., factors of ten). For example, there is one order of magnitude between 2 and 20, and two orders of magnitude between 2 and 200. Each division or multiplication by 10 is called an order of magnitude. This phrasing helps quickly express the difference in scale between 2 and 2,000,000: they di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
