  2. Constellation diagram - Wikipedia

    en.wikipedia.org/wiki/Constellation_diagram

    When plotted on a constellation diagram the point representing that received sample will be offset from the correct position for that symbol. An electronic test instrument called a vector signal analyzer can display the constellation diagram of a digital signal by sampling the signal and plotting each received symbol as a point. The result is a ...

  3. Convergence tests - Wikipedia

    en.wikipedia.org/wiki/Convergence_tests

    exists there are three possibilities: if L > 1 the series converges (this includes the case L = ∞) if L < 1 the series diverges. and if L = 1 the test is inconclusive. An alternative formulation of this test is as follows. Let { an } be a series of real numbers. Then if b > 1 and K (a natural number) exist such that.

  4. Dirichlet's test - Wikipedia

    en.wikipedia.org/wiki/Dirichlet's_test

    An analogous statement for convergence of improper integrals is proven using integration by parts. If the integral of a function f is uniformly bounded over all intervals , and g is a non-negative monotonically decreasing function , then the integral of fg is a convergent improper integral.

  5. Monte Carlo method - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_method

    The approximation of a normal distribution with a Monte Carlo method. Monte Carlo methods, or Monte Carlo experiments, are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle.

    The test was published in 1946, and is now currently in its 5th edition. Testing Test format A sample design used in Administration M of the Benton Test. The original design is shown at the top, and after a delay, the four design choices are shown and the subject is asked to choose the one that best matches the original design.

  7. Bender-Gestalt Test - Wikipedia

    en.wikipedia.org/wiki/Bender-Gestalt_Test

    The Bender Visual-Motor Gestalt Test (abbreviated as Bender-Gestalt test) is a psychological test used by mental health practitioners that assesses visual-motor functioning, developmental disorders, and neurological impairments in children ages 3 and older and adults. The test consists of nine index cards picturing different geometric designs.

  8. Radar chart - Wikipedia

    en.wikipedia.org/wiki/Radar_chart

    The radar chart is a chart and/or plot that consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points.

  9. Golovin–Sivtsev table - Wikipedia

    en.wikipedia.org/wiki/Golovin–Sivtsev_table

    The Golovin–Sivtsev table ( Russian: Таблица Головина-Сивцева) is a standardized table for testing visual acuity, which was developed in 1923 by Soviet ophthalmologists Sergei Golovin and D. A. Sivtsev. [1] In the USSR, it was the most common table of its kind, and as of 2008 its use is still widespread in several post ...
