  2. Continuity test - Wikipedia

    en.wikipedia.org/wiki/Continuity_test

    In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.

  3. Continuity tester - Wikipedia

    en.wikipedia.org/wiki/Continuity_tester

    Entry-level cable testers are essentially continuity testers. A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; [1] that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus. [1]

  4. Yates's correction for continuity - Wikipedia

    en.wikipedia.org/wiki/Yates's_correction_for...

    In statistics, Yates's correction for continuity (or Yates's chi-squared test) is used in certain situations when testing for independence in a contingency table.

  5. Cable tester - Wikipedia

    en.wikipedia.org/wiki/Cable_tester

    There are two common ways to test a connection: A continuity test. Current is passed down the connection. If there is current the connection is assumed to be good. This type of test can be done with a series combination of a battery (to provide the current) and a light bulb (that lights when there is a current). A resistance test. A known ...

  6. McNemar's test - Wikipedia

    en.wikipedia.org/wiki/McNemar's_test

    The exact binomial test gives p = 0.053 and McNemar's test with continuity correction gives = 3.68 and p = 0.055. The asymptotic McNemar's test gives = 4.55 and p = 0.033 and the mid-P McNemar's test gives p = 0.035. Both the McNemar's test and mid-P version provide stronger evidence for a statistically significant treatment effect in this ...

  7. Modulus of continuity - Wikipedia

    en.wikipedia.org/wiki/Modulus_of_continuity

    A sublinear modulus of continuity can easily be found for any uniformly continuous function which is a bounded perturbation of a Lipschitz function: if f is a uniformly continuous function with modulus of continuity ω, and g is a k Lipschitz function with uniform distance r from f, then f admits the sublinear module of continuity min{ω(t), 2r ...

    Earth continuity test: this test is to make sure the earthing system is properly connected Live testing. Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified by standards Insulation resistance testing
