  2. Order of approximation - Wikipedia

    en.wikipedia.org/wiki/Order_of_approximation

    First-order approximation is the term scientists use for a slightly better answer. [3] Some simplifying assumptions are made, and when a number is needed, an answer with only one significant figure is often given ("the town has 4 × 10 3, or four thousand, residents"). In the case of a first-order approximation, at least one number given is exact.

  3. Just-noticeable difference - Wikipedia

    en.wikipedia.org/wiki/Just-noticeable_difference

    In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time. [1]

  4. Shaping (psychology) - Wikipedia

    en.wikipedia.org/wiki/Shaping_(psychology)

    Shaping is a conditioning paradigm used primarily in the experimental analysis of behavior.The method used is differential reinforcement of successive approximations.It was introduced by B. F. Skinner [1] with pigeons and extended to dogs, dolphins, humans and other species.

  5. Approximation - Wikipedia

    en.wikipedia.org/wiki/Approximation

    Approximation is a key word generally employed within the title of a directive, for example the Trade Marks Directive of 16 December 2015 serves "to approximate the laws of the Member States relating to trade marks". [11] The European Commission describes approximation of law as "a unique obligation of membership in the European Union". [10]

  6. Order of accuracy - Wikipedia

    en.wikipedia.org/wiki/Order_of_accuracy

    In numerical analysis, order of accuracy quantifies the rate of convergence of a numerical approximation of a differential equation to the exact solution. Consider u {\displaystyle u} , the exact solution to a differential equation in an appropriate normed space ( V , | | | | ) {\displaystyle (V,||\ ||)} .

  7. Approximate number system - Wikipedia

    en.wikipedia.org/wiki/Approximate_number_system

    The approximate number system (ANS) is a cognitive system that supports the estimation of the magnitude of a group without relying on language or symbols. The ANS is credited with the non-symbolic representation of all numbers greater than four, with lesser values being carried out by the parallel individuation system, or object tracking system. [1]

  8. Second-order - Wikipedia

    en.wikipedia.org/wiki/Second-order

    Second order approximation, an approximation that includes quadratic terms; Second-order arithmetic, an axiomatization allowing quantification of sets of numbers; Second-order differential equation, a differential equation in which the highest derivative is the second; Second-order logic, an extension of predicate logic

  9. Order of magnitude - Wikipedia

    en.wikipedia.org/wiki/Order_of_magnitude

    Order of magnitude is a concept used to discuss the scale of numbers in relation to one another. 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. [1] For example, 1 and 1.02 are within an order of magnitude.
