  2. Cohen's kappa - Wikipedia

    en.wikipedia.org/wiki/Cohen's_kappa

    Cohen's kappa measures the agreement between two raters who each classify N items into C mutually exclusive categories. The definition of is =, where p o is the relative observed agreement among raters, and p e is the hypothetical probability of chance agreement, using the observed data to calculate the probabilities of each observer randomly selecting each category.

  3. Heat capacity ratio - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity_ratio

    In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).

  4. Fleiss' kappa - Wikipedia

    en.wikipedia.org/wiki/Fleiss'_kappa

    Statistical packages can calculate a standard score (Z-score) for Cohen's kappa or Fleiss's Kappa, which can be converted into a P-value. However, even when the P value reaches the threshold of statistical significance (typically less than 0.05), it only indicates that the agreement between raters is significantly better than would be expected ...

    en.wikipedia.org/wiki/Rüchardt_Experiment

    The Rüchardt experiment, [1] [2] [3] invented by Eduard Rüchardt, is a famous experiment in thermodynamics, which determines the ratio of the molar heat capacities of a gas, i.e. the ratio of (heat capacity at constant pressure) and (heat capacity at constant volume) and is denoted by (gamma, for ideal gas) or (kappa, isentropic exponent, for real gas).

  7. Relative permittivity - Wikipedia

    en.wikipedia.org/wiki/Relative_permittivity

    Relative permittivity is typically denoted as ε r (ω) (sometimes κ, lowercase kappa) and is defined as = (), where ε(ω) is the complex frequency-dependent permittivity of the material, and ε 0 is the vacuum permittivity.
