Mead's resource equation

(noun)

$E=N-B-T$: an equation that gives a hint of what the appropriate sample size is, where parameters such as expected standard deviations or expected differences in values between groups are unknown or very hard to estimate.

    • As follows, this can be estimated by pre-determined tables for certain values, by Mead's resource equation, or, more generally, by the cumulative distribution function.
    • Mead's resource equation is often used for estimating sample sizes of laboratory animals, as well as in many other laboratory experiments.
    • All the parameters in the equation are in fact the degrees of freedom of the number of their concepts, and hence, their numbers are subtracted by 1 before insertion into the equation.
