  2. Round-off error - Wikipedia

    en.wikipedia.org/wiki/Round-off_error

    Round-by-chop: The base-expansion of is truncated after the ()-th digit. This rounding rule is biased because it always moves the result toward zero. Round-to-nearest: () is set to the nearest floating-point number to . When there is a tie, the floating-point number whose last stored digit is even (also, the last digit, in binary form, is equal ...

    en.wikipedia.org/wiki/Overpressure_ammunition

    Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.

  4. Talk:Margin of error - Wikipedia

    en.wikipedia.org/wiki/Talk:Margin_of_error

    i assume here that you mean q = 1-p; why then not make the substitution p - q = p - (1-p) = 2 p -1; so variance = 4*p*(1-p)/N. that reads a lot simpler than the complicated formula you provide. i generally like this article, and agree that it is a subject woefully misunderstood by the public & press.

  5. p-value - Wikipedia

    en.wikipedia.org/wiki/P-value

    In null-hypothesis significance testing, the p-value [note 1] is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct. [2] [3] A very small p-value means that such an extreme observed outcome would be very unlikely under the null hypothesis.

  6. Percentage point - Wikipedia

    en.wikipedia.org/wiki/Percentage_point

    A percentage point or percent point is the unit for the arithmetic difference between two percentages.For example, moving up from 40 percent to 44 percent is an increase of 4 percentage points (although it is a 10-percent increase in the quantity being measured, if the total amount remains the same). [1]

  7. Randomized rounding - Wikipedia

    en.wikipedia.org/wiki/Randomized_rounding

    In computer science and operations research, randomized rounding [1] is a widely used approach for designing and analyzing approximation algorithms. [2] [3]Many combinatorial optimization problems are computationally intractable to solve exactly (to optimality).

    The first thousand values of φ(n).The points on the top line represent φ(p) when p is a prime number, which is p − 1. [1]In number theory, Euler's totient function counts the positive integers up to a given integer n that are relatively prime to n.
