    LOINC. 5639-0, 5640-8, 15120-9, 56478-1. Blood alcohol content ( BAC ), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [ 1] BAC is expressed as mass of alcohol per volume of blood.

  3. Standard normal table - Wikipedia

    en.wikipedia.org/wiki/Standard_normal_table

    Standard normal table. In statistics, a standard normal table, also called the unit normal table or Z table, [ 1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal ...

  4. Basic reproduction number - Wikipedia

    en.wikipedia.org/wiki/Basic_reproduction_number

    Basic reproduction number. is the average number of people infected from one other person. For example, Ebola has an of two, so on average, a person who has Ebola will pass it on to two other people. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate ...

    en.wikipedia.org/wiki/Equals_sign

    The equals sign ( British English) or equal sign ( American English ), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. [ 1] In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the ...

  6. Henry (unit) - Wikipedia

    en.wikipedia.org/wiki/Henry_(unit)

    The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...

  7. Quantile - Wikipedia

    en.wikipedia.org/wiki/Quantile

    Quantile. Probability density of a normal distribution, with quantiles shown. The area below the red curve is the same in the intervals (−∞,Q1), (Q1,Q2), (Q2,Q3), and (Q3,+∞). In statistics and probability, quantiles are cut points dividing the range of a probability distribution into continuous intervals with equal probabilities, or ...

  8. Power (statistics) - Wikipedia

    en.wikipedia.org/wiki/Power_(statistics)

    In the trivial case of zero effect size, power is at a minimum and equal to the significance level of the test , in this example 0.05. For finite sample sizes and non-zero variability, it is the case here, as is typical, that power cannot be made equal to 1 except in the trivial case where α = 1 {\displaystyle \alpha =1} so the null is always ...

  9. Accuracy and precision - Wikipedia

    en.wikipedia.org/wiki/Accuracy_and_precision

    In cognitive systems, accuracy and precision is used to characterize and measure results of a cognitive process performed by biological or artificial entities where a cognitive process is a transformation of data, information, knowledge, or wisdom to a higher-valued form.
