  2. Benford's law - Wikipedia

    en.wikipedia.org/wiki/Benford's_law

    The interval [log 1, log 2] is much wider than the interval [log 9, log 10] (0.30 and 0.05 respectively); therefore if log x is uniformly and randomly distributed, it is much more likely to fall into the wider interval than the narrower interval, i.e. more likely to start with 1 than with 9; the probabilities are proportional to the interval ...

  3. p-value - Wikipedia

    en.wikipedia.org/wiki/P-value

    In a significance test, the null hypothesis is rejected if the p-value is less than or equal to a predefined threshold value , which is referred to as the alpha level or significance level. α {\displaystyle \alpha } is not derived from the data, but rather is set by the researcher before examining the data.

  4. Radiative forcing - Wikipedia

    en.wikipedia.org/wiki/Radiative_forcing

    Radiative forcing is defined in the IPCC Sixth Assessment Report as follows: "The change in the net, downward minus upward, radiative flux (expressed in W/m 2) due to a change in an external driver of climate change, such as a change in the concentration of carbon dioxide (CO 2), the concentration of volcanic aerosols or the output of the Sun." [3]: 2245

  5. List of sovereign states by wealth inequality - Wikipedia

    en.wikipedia.org/wiki/List_of_sovereign_states...

    Higher Gini coefficients signify greater wealth inequality, with 0 being complete equality, whereas a value near 1 can arise if everybody has zero wealth except a very small minority. Countries that have high-quality wealth taxes and honest reporting from financial institutions, such as the Netherlands and Norway , tend to have more reliable ...

  7. Letter frequency - Wikipedia

    en.wikipedia.org/wiki/Letter_frequency

    The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...

  8. Young's modulus - Wikipedia

    en.wikipedia.org/wiki/Young's_modulus

    Young's modulus is the slope of the linear part of the stress–strain curve for a material under tension or compression.. Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise.
