    The result would be that the GDP in 2000 equals $300 million × 1 ⁄ 2 = $150 million, in 1990 monetary terms. We would see that the country's GDP had realistically increased 50 percent over that period, not 200 percent, as it might appear from the raw GDP data.

  4. 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]

    For example, when testing the null hypothesis that a distribution is normal with a mean less than or equal to zero against the alternative that the mean is greater than zero (:, variance known), the null hypothesis does not specify the exact probability distribution of the appropriate test statistic.

    en.wikipedia.org/wiki/Container_ship

    A container ship (also called boxship or spelled containership) is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.

    Bra size (also known as brassiere measurement or bust size) indicates the size characteristics of a bra. While there is a number of bra sizing systems in use around the world, the bra sizes usually consist of a number, indicating the size of the band around the woman's torso , and one or more letters that indicate the breast cup size.

  8. Exponential growth - Wikipedia

    en.wikipedia.org/wiki/Exponential_growth

    So for an algorithm of time complexity 2 x, if a problem of size x = 10 requires 10 seconds to complete, and a problem of size x = 11 requires 20 seconds, then a problem of size x = 12 will require 40 seconds. This kind of algorithm typically becomes unusable at very small problem sizes, often between 30 and 100 items (most computer algorithms ...

  9. Effect size - Wikipedia

    en.wikipedia.org/wiki/Effect_size

    In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of a parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
