  2. Fisher's method - Wikipedia

    en.wikipedia.org/wiki/Fisher's_method

    Under Fisher's method, two small p-values P 1 and P 2 combine to form a smaller p-value.The darkest boundary defines the region where the meta-analysis p-value is below 0.05.. For example, if both p-values are around 0.10, or if one is around 0.04 and one is around 0.25, the meta-analysis p-value is around 0

  3. Law of the unconscious statistician - Wikipedia

    en.wikipedia.org/wiki/Law_of_the_unconscious...

    In probability theory and statistics, the law of the unconscious statistician, or LOTUS, is a theorem which expresses the expected value of a function g(X) of a random variable X in terms of g and the probability distribution of X. The form of the law depends on the type of random variable X in question. If the distribution of X is discrete and ...

  4. Planck constant - Wikipedia

    en.wikipedia.org/wiki/Planck_constant

    Planck was able to calculate the value of from experimental data on black-body radiation: his result, 6.55 × 10 −34 J⋅s, is within 1.2% of the currently defined value. [2] He also made the first determination of the Boltzmann constant k B {\displaystyle k_{\text{B}}} from the same data and theory.

  5. Poisson distribution - Wikipedia

    en.wikipedia.org/wiki/Poisson_distribution

    The variance of the binomial distribution is 1 − p times that of the Poisson distribution, so almost equal when p is very small. The word law is sometimes used as a synonym of probability distribution, and convergence in law means convergence in distribution. Accordingly, the Poisson distribution is sometimes called the "law of small numbers ...

  6. Ideal gas law - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas_law

    Under these conditions, p 1 V 1 γ = p 2 V 2 γ, where γ is defined as the heat capacity ratio, which is constant for a calorifically perfect gas. The value used for γ is typically 1.4 for diatomic gases like nitrogen (N 2) and oxygen (O 2), (and air, which is 99% diatomic).

  7. Golden ratio - Wikipedia

    en.wikipedia.org/wiki/Golden_ratio

    [a] The constant satisfies the quadratic equation = + and is an irrational number with a value of [1] φ = 1 + 5 2 = {\displaystyle \varphi ={\frac {1+{\sqrt {5}}}{2}}=} 1.618 033 988 749 .... The golden ratio was called the extreme and mean ratio by Euclid , [ 2 ] and the divine proportion by Luca Pacioli , [ 3 ] and also goes by several other ...

  8. Binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Binomial_distribution

    The binomial distribution is the PMF of k successes given n independent events each with a probability p of success. Mathematically, when α = k + 1 and β = n − k + 1, the beta distribution and the binomial distribution are related by [clarification needed] a factor of n + 1:

  9. Marchenko–Pastur distribution - Wikipedia

    en.wikipedia.org/wiki/Marchenko–Pastur...

    Marchenko–Pastur distribution. In the mathematical theory of random matrices, the Marchenko–Pastur distribution, or Marchenko–Pastur law, describes the asymptotic behavior of singular values of large rectangular random matrices. The theorem is named after soviet mathematicians Volodymyr Marchenko and Leonid Pastur who proved this result ...
