There are many longstanding unsolved problems in mathematics for which a solution has still not yet been found. The notable unsolved problems in statistics are generally of a different flavor; according to John Tukey, [1] "difficulties in identifying problems have delayed statistics far more than difficulties in solving problems."
The Multidimensional Aptitude Battery II is a group-administered intelligence test created by psychologist Douglas N. Jackson which is supposed to measure Verbal, Performance and Full Scale IQ. The battery consists of 10 subtests and is used for various professional, medical, military, government, law enforcement and employment settings.
The General Aptitude Test Battery (GATB) is a work-related cognitive test developed by the U.S. Employment Service (USES), a division of the Department of Labor. It has been extensively used to study the relationship between cognitive abilities, primarily general intelligence , and job performance .
The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces.
It consists of 50 multiple choice questions to be answered in 12 minutes. [1] [2] [3] The score is calculated as the number of correct answers given in the allotted time, and a score of 20 is intended to indicate average intelligence. [2] The most recent version of the test is WonScore, a cloud-based assessment providing a score to potential ...
Graphs of probabilities of getting the best candidate (red circles) from n applications, and k/n (blue crosses) where k is the sample size. The secretary problem demonstrates a scenario involving optimal stopping theory [1] [2] that is studied extensively in the fields of applied probability, statistics, and decision theory.
Dantzig is known for his development of the simplex algorithm, [1] an algorithm for solving linear programming problems, and for his other work with linear programming. In statistics , Dantzig solved two open problems in statistical theory , which he had mistaken for homework after arriving late to a lecture by Jerzy Spława-Neyman .
The question is whether or not, for all problems for which an algorithm can verify a given solution quickly (that is, in polynomial time), an algorithm can also find that solution quickly. Since the former describes the class of problems termed NP, while the latter describes P, the question is equivalent to asking whether all problems in NP are ...
