Two values of this quantity are compared in a two-sample t-test.
Two values of this quantity are compared in a two-sample t-test. In a chi-squared [KYE "squared"] distribution, this value is equal to the number of degrees of freedom. For a function, this value can be calculated by dividing its integral by the width of the interval of the integral. Often represented by a letter with a bar over it, this number for a distribution is equal to the expected value. There are harmonic and geometric versions of this quantity, the latter of which is found by taking the root of a product. Name this value found by adding a set of numbers and dividing by the number of values in the set.
