  2. IQ classification - Wikipedia

    en.wikipedia.org/wiki/IQ_classification

    Wechsler changed a few of the boundaries for classification categories and a few of their names compared to the 1958 version of the test. The test's manual included information about how the actual percentage of people in the norming sample scoring at various levels compared to theoretical expectations.

  3. Upper and lower bounds - Wikipedia

    13934 and other numbers x such that x ≥ 13934 would be an upper bound for S. The set S = {42} has 42 as both an upper bound and a lower bound; all other numbers are either an upper bound or a lower bound for that S. Every subset of the natural numbers has a lower bound since the natural numbers have a least element (0 or 1, depending on ...

  4. Rough set - Wikipedia

    en.wikipedia.org/wiki/Rough_set

    The tuple _, ¯ composed of the lower and upper approximation is called a rough set; thus, a rough set is composed of two crisp sets, one representing a lower boundary of the target set , and the other representing an upper boundary of the target set .

    Even if you’re squeaking into the upper class (the 80-90% range), you’re looking at about $793,000. Moving down to the middle class , things get a bit more varied.

  6. Minkowski's bound - Wikipedia

    en.wikipedia.org/wiki/Minkowski's_bound

    Since the number of integral ideals of given norm is finite, the finiteness of the class number is an immediate consequence, [1] and further, the ideal class group is generated by the prime ideals of norm at most M K. Minkowski's bound may be used to derive a lower bound for the discriminant of a field K given n, r 1 and r 2.

  9. Plastic limit theorems - Wikipedia

    en.wikipedia.org/wiki/Plastic_limit_theorems

    The two plastic limit theorems apply to any elastic-perfectly plastic body or assemblage of bodies. Lower limit theorem: If an equilibrium distribution of stress can be found which balances the applied load and nowhere violates the yield criterion, the body (or bodies) will not fail, or will be just at the point of failure.
